My home automation projects has been churning along for over a year now. I’ve been able to set up motion detectors for stairway lights, LED strips for colorful lighting, and voice control integration through the whole house. Even my wife admits that having voice control in every room is convenient as heck.
We’ve gotten very used to the ability to turn on or off all the lights in an area, like saying “Downstairs lights off” which shuts off the 3 lamps in the living room as well as the kitchen and dining room lights.
But one thing that has been a steady thorn in my side is the difficulty setting up a wall mounted tablet to show the status of the lights, heating, and motion detectors, and allow you to turn things on and off via this panel.
Nowadays most folks use tablets – anything from an iPad down to the cheapest Android tablet you can find. They work fine, but for me the problem has always been power. The tablet needs to be turned on full time, and to do that, you need power. Running power to a spot in the middle of the wall is problematic and cumbersome. This is doubly irritating in that most tablets only require a simple USB cable to keep running.
This lack of easy access to power has stalled my ‘tablet’ rollout for quite a while, until I found this combination USB port / lightswitch from Bryant Electric (model USBB102W). Using this plus a short jump cable, it seemed possible to mount the tablet just over the light switch. And lo, it was!
The lightswitch was a basic “interruptor” – it was wired with 2 black wires, plus a ground. The black wire is the “hot” feed to the ceiling fixture, so opening or closing the switch would open or close the circuit. Fortunately, the people who wired the house also had a neutral wire in there. It wasn’t wired to teh switch, but had a 6 way insertion connector, so it would be easy to wire it up.
Once I had the fitting apart, the wiring on the new USB enabled switch was a little confusing. Fortunately, I found a very nice post (on Amazon’s feedback page interestingly enough) that described how to wire it up:
I was able to replace the press-in connector on the neutral lines with a wirenut, and used proper gauge for the jumper. Reset the breakers, and yay! Everything works!
Once I reassembled the switch and put a new plate on it, I was ready to mount the tablet. I’ve been using ActionTiles to control Smartthings connected devices, so putting that on the tablet was the goal. I ordered a couple short USB cables (making sure the orientation would work for the tablet), and then 3d printed some wall brackets for the tablet. A little VHB tape later, my tablet was mounted and working!
I enabled developer mode on the tablet, and set it to ‘never turn off while plugged in’, and my setup was complete!
So now what?
So where to next? Well, doing the Alexa integration with Smartthings is cumbersome (I’ll write this up at some point). I’ll need to solve this at some point – Alexa is just too useful to have, but the lack of a programmatic API for integrating display devices (like this one) with it is a problem (You can use a ‘kindle fire’ tablet for this, but the interface is not good, and ONLY controls Alexa devices :-/. Same problem, just in reverse.
I also want to add more items to the display board – like indicators about the status of my motion detectors, and possible a camera feed to the front porch. We’ll see!
The Toyota Prius Prime. In so many ways, a remarkable piece of engineering. Efficient, comfortable, and not so bad in the cargo territory. In it’s plugin form, it can run 20-25 miles on pure EV power, and after that, it still chugs along at 40mpg. For people wanting to dip their toes into the electric vehicle world, it’s not a bad place to start, assuming you’re okay with the styling.
With all that, what the HELL went wrong when they ‘designed’ the dashboard and the information systems?
I’m rarely speechless when it comes to engineering projects, particularly ones backed by such a well respected and successful company as Toyota. But jumpin jehosephat. Who the heck designed the dashboard? It’s… it’s… nnnnng…. well… let me show you.
The Dashboard – An Introduction
First, lets take a look at the interior. This is the 2019 Prius Prime dashboard, directly from Toyota’s brochure…
Now before I go straight to the jugular, lets note a few positive aspects here.
A large, centrally located touchscreen. I like that. It’s easy to reach, everyone in the car can see it, it’s bright and visible.
The steering wheel has easy to reach controls, right under the thumbs. Nice.
The upper display (directly in front of the window) has 3 smaller screens that can show a variety of information panels. The most obvious one is a speedometer, but the other options are battery usage, mileage, map directions, etc. As compared to the Tesla, which puts everything on one display in the middle of the car, these secondary displays that ALWAYS display certain information is a nice touch.
Well, that’s nice, but what’s your beef?
Sounds all peachy so far, right? I mean, it looks all shiny and clean, so what’s wrong?
Turns out, plenty.
Lets start at the meta level. That big central display? It only controls a small subset of the car systems. It’s a bad design to have to go hunting for an external button or switch or toggle or display to get a basic function that the display should have on it.
Another problem with the central display are the buttons on the glass on either side. Those are flush contacts. You have to look at them to determine if you’re pushing them, and there’s no feedback when you do. Talk about distracted driver problems. No feedback contact buttons should be used VERY CAREFULLY in motor vehicles. Why some of these buttons are glass and others in the car are standard switches, I have no idea.
Okay, but lets hear the real fails.
Okay, you asked for it, lets start running down some absolutely batshit decisions made on this car.
Lets start simple. Seat heaters. Everyone loves ’em, right? Took us literally googling and watching youtube videos to figure out how to turn them on. The controls for the seat heaters are tucked under the dash, on either side of the central console. Once I scrunched down in the seat, bent my head to one side, I was able to see them. My wife, who is a foot and a half shorter than I am, never saw them either. Who thought this was the appropriate placement for these switches?
Remember those little screens under the front windshield? Nice, aren’t they? Well, they are configurable. You can change what each one shows. At some point, my wife brought up “Hey, that middle display used to show how much battery time I had left, now it doesn’t. How do you change that?” – I, a systems engineer, could absolutely not figure out how to change those displays. The answer? Tap the right arrow on the steering wheel right control pad. No other feedback that this is how to do this – no menus, no prompts, no information – I had to google this one too. There’s nothing on that nice big central display that lets you configure these smaller displays. They are completely separate.
At one point we were driving around at night, and I was wondering why the central screen was so bright. Most cars switch into ‘night mode’ when it gets dark, but this screen was blazing white. Going through all the menus, I found a screen setting for ‘DAY MODE’ ON/OFF – what exactly that means is sort of a mystery. There was no NIGHT MODE ON/OFF. Just that one toggle. Turns out, you need to use the OTHER screen control. The one on the left side of the steering column around knee height. There’s a dial there that on older cars would set the brightness of the dashboard instruments. Some bright engineer at Toyota decided that if that little knob was spun to a certain point, the central console would always be in day mode. the DAY MODE apparently can override this setting? Who knows – but having to go off-screen to some random control when the option should have been RIGHT THERE on the screen is definitely a fail.
Backup beeper. Did you know the Prius has a backup beeper? Going by Wikipedia :
A back-up beeper, also known as back-up alarm or vehicle motion alarm, is a device intended to warn passers-by of a vehicle moving in reverse. They typically produce 1000 Hz pure tone beeps at 97-112 decibels. Matsusaburo Yamaguchi of Yamaguchi Electric Company, Japan, invented the back-up beeper. It was first manufactured as model BA1 in 1963. ISO 6165 describes “audible travel alarms”, and ISO 9533 describes how to measure the performance of the alarms
Great idea, right? Except the Prius backup beeper SOUNDS INSIDE THE CAR. Not externally. You can’t hear it outside. Who exactly is this supposed to be warning?
The mapping software sucks. I mean, you just can’t get around it. It’s cumbersome, it’s painful to use, the search functions are absolute shit, and it’s just a nightmare to try and use productively. Took us another zillion years to figure out how to turn off the turn by turn navigation (you can’t except via a buried setting – makes listening to music really terrifying – why can’t you just say ‘turn off turn by turn for now, I’m listening to something cool, I don’t need the interruptions telling me that I’ll be on this interstate until the heat death of the universe.’
Most functions are disabled while in motion. This seems to carry over from day 0 of cars getting anything more complicated than an FM stereo head unit. Someone somewhere said “We should disable any function that may be a distraction to the driver, with no option to get around it”, and so it was. But, what if you’re traveling in a modern vehicle that thoughtfully placed the navigation system between the driver and passenger seat, where the passenger has the same access as the driver, wouldn’t it make sense to allow the passe… NOPE! Locked out! You can’t modify your route or destination or settings while in motion. DENIED.
I’m sure I’ll be adding to this list as more things come up. What’s bothersome about all this is so much of this can be fixed in software. But as far as I can tell, Toyota is following the auto manufacturer trend of assuming once a model year of a car is complete, so is the software, and it doesn’t need to change. They may do minor tweaks and fixes, but they do not actually revise the systems with major improvements (unlike Tesla, who put out major software updates pretty much constantly, frequently adding new features or overhauling others).
It may sound like I’m bashing Toyota and ignoring flaws in other manufacturers. That’s not the case at all. I’ve written in the past about my issues with the Tesla Model 3, and while I didn’t have a lot of complaints about my Chevy Volt, there were some frustrations with GM. (In fact, I had some UX problems with the Volt as well, but the Volt didnt’ have the big touchscreen that SHOULD have made those problems easy to fix.)
Modern car manufacturers absolutely need to get on board, and stop thinking of the dashboard with a touchscreen as just a ‘shiny’ version of the old knobs and dials dashboards. It’s a fully functioning digital information and control system, and should be treated as such, with regular updates, and some put into UX design. Tesla is the only company that is doing this right. What the heck is everyone else thinking?
About 6 months ago I bought a Creality CR-10 3d Printer. All the cool kids were using 3d printers for just abouyt everything, I was starting to feel left out. Our makerspace has some great printers, but with the pandemic (and also that the space was 45 minutes away), I wanted something nearby that I could tinker with on my own time.
Secondarily, there’s something attractive about being your own fabricator. Having a printer means I can manufacture my own items. That’s pretty cool. I needed to learn how to do that.
For the most part, the printer works great. 3d printing with PLA is not a fast process. Most prints take hours to complete. The CR-10 worked like a champ though. Prints were clean, the end results were useable, and the machine was dependable and easy to manage. I learned to use Ultimaker Cura to set up the jobs and all was well.
I didn’t print anything for a month or so, then went back to print some cable runners to try and organize my desk wiring a bit. When home-ing the print bed, I heard a sort of chattering / stuttering noise during Y axis motion:
I didn’t think much about it, but the print failed with layers shifting in a weird way. Obviously something was wrong.
I spent some time trying to find problems with wiring, stuff blocking the motion of the stepper – nothing was obvious. It was weird though, because the chattering would only happen in one direction, and even odder, it happened when the printer was completely powered off. Moving the bed by hand would cause this sound even when nothing was powered up.
Yesterday I decided enough was enough. Posting on reddit asking for help got no good feedback. I submitted a bug report to Creality, unsurprisingly, I never even got an acknowledgement to the message. I chatted with friends who suggested stepper motor failure, bed misalignment, power supply problems – a whole host of things. None of these were it.
Turns out, like so many things, it was something stupid.
On the front of the Y axis travel arm, there’s a bracket that holds the pully for the belt. This bracket ‘sticks out’ from the frame of the printer, and apparently, somewhere along the line, I had bumped into this bracket, pushing it down about a cm. That was enough to have the belt rub against the end of the track. Travel in one direciton was smooth, but in the other, the teeth on the belt would catch on the end of the track.
The answer of course was to just move the assembly up into the right position, and BEHOLD! No chattering, no stuttering, no problems. Thus ended a month of having the printer mocking me in its uselessness.
I did, however, run into one other problem. Bed levelling is the nemesis of any 3d printer owner. It can be tedious and time consuming, but is absolutely critical to getting good, solid, well formed prints.
On the CR-10, levelling is accomplished via a set of wheels under the bed that compress set of strong springs to get the bed where you want it. In this case, the springs were 100% compressed, and I couldn’t get enough clearance between the glass and the print head. In the past I was able to wrangle enough slack to make it happen, but today, maybe due to humidity or whatever, I just couldnt’ get it to clear.
I solved the problem by essentially raising the 0 position on the Z axis stepper. Because there’s no built-in function to do this on the printer, but being the ever adaptive type, I made do with 4 strips of electrical tape, added to the Z gantry just above the homing switch. This effectively told the printer to stop the the print head about a mm higher than it had before, thus giving me some working room to adjust the bed
I really do like the CR-10. When it’s running, it’s rock solid, and prints like a dream. I’m hoping to do some mods to it once the office situation settles down a few notches, but right now I’m just happy to have a working, non-chattery, dependable machine again.
When PCs were hitting their stride, handheld versions were starting to make their appearances. The early versions were pretty limited in their performance, but they were functional, mobile, and not too bad.
A fellow on one of the retro forums reached out to me recently and asked if I’d be interested in a Zeos Pocket PC. At first I thought it was another Windows CE machine, and I was really avoiding those. But this turns out to be a very basic DOS based handheld, so I said “Sure, I’ll take it!”
The Zeos Pocket PC was made in 1992, around the time the HP 95LX and similar ‘clamshell’ computers were being manufactured.
Original price: $595 ($1,108 in 2020 dollars)
CPU: NEC V30 (80C86) @ 4.77MHz / 7.15MHz
Memory: 640k RAM
Display: 80×25 LCD text, 640×200 graphics
Batteries: Two AA
The Zeos PC has a couple features on it that make it pretty interesting. The first is it has a parallel and a serial port on it. Unfortunately, they use a custom cable connector (which I happen to have), so connecting up to them can be a little challenging.
However, they also have dual PCMCIA slots, which means it’s easy to dock new cards into it (conveniently located under the case). The Zeos supports SRAM cards… these cards are Type 1 PCMCIA devices, which are pretty hard to find, and require a battery in the card to retain their storage. I have 1-2 that I use on my Newtons, so I’m looking forward to tinkering with them.
Another neat feature is it has a quite large and comfortable keyboard. That can be a win or lose – easy to type on, but it makes the entire unit quite bulky. Not something that would fit comfortably in a jacket pocket
The screen is not particularly easy to work with. It has no backlighting, so visibility requires just the right light setup (a direct light, but not one that reflects badly).
It is, however, extremely light and portable for a fully functional PC-DOS machine from 1991.
The Zeos Pocket PC is a cute representation of the state of DOS based computers in the early 90’s. Extremely limited funtionally in it’s basic state, but I’m going to see if I can get some simple applications on it. It comes with Works (an extremely simple software suite for notes and stuff), but it might be fun to get some more complex applications on it and get some connectivity going.
I really don’t like making New Years Resolutions. It always strikes me as something people do because.. “it’s a thing you do”.
This year though, I inadvertently made one, and it’s turning out to be a good thing.
Over the winter vacation, I had a great conversation with my wife that ranged all over, and was one of those conversations that can be a turning point. The topic was “What is it that’s important to you? What makes you happy?”
Turns out, something that made me happy was definitely not taking a bigger role. I wasn’t making time for it, so it was falling behind.
Fifteen or so years ago I was in a blues band, playing bass, and having a great time. We were gigging out, we were playing the most god awful bars you could find, but it was fun, and while there were times it was challenging, there were also times of great joy… those moments when things just come together and we rocked the place.
Because of my work schedule, I had to leave the band (lots of travel makes it hard to stay on the performance schedule), and music sort of fell on the wayside. I still had my guitars, I still played… a little, but I definitely stopped growing and learning. Things slowed down.
My kid is getting pretty serious about their music, and has been steadily pushing me to play more. I’ve been resisting under the normal arguments “I suck, I don’t know enough, I’m embarrassed). We’ve played a few times, and it made me sad, because what I knew was too limited, too constrained. And my fingers hurt.
Over the winter break, after that conversation with my wife, I decided it was time to change that. Music is something I truly love, I just never made the choice to dedicate time and energy into learning in all the things I didn’t know, and… of course, I needed to PRACTICE.
So, since somewhere around New Years, I’ve thrown myself into finally learning guitar properly. YouTube is a wonderful source of lessons, demonstrations, and backing tracks. That, coupled with help from Zach, and lots of practice, I’m starting to fill in the gaps in my guitar knowledge that was sorely lacking.
But, most importantly of all, I’ve been sticking with a regular practice schedule with a very simple rule. Play every day. Even if it’s only 10 minutes… pick up an instrument, and run scales, run fingering exercises, play some part of a song. Keep your fingers active, keep the knowledge alive, and keep building.
Since January, I’ve held to this schedule. I play every day. Sometimes 10 minutes, sometimes an hour or two. What’s happened is my fingers are building up calluses, and I’m learning pick and finger control – things I never had before. I’m learning to solo, something that’s always been a mystery to me. Music theory is filling in, though very slowly, and with the possible pitfall a lot of guitarists fall into. A lot of theory on guitar matches to patterns and arrangements on the neck. The theory is subsumed by learning patterns and relationships between positions, rather than the theory itself and how the neck represents it. I’m okay with this for now, but I recognize I’ll need to fill things in later.
I’ve also invested in a new (to me) guitar. It’s an Ovation Balladeer, made in 1972. I’ve always had a weak spot for Ovations, and even though they’re not the magic they were once considered, I still love the feel, styling, and sound of them. I found one on Craigslist that, unfortunately, had a broken headstock. It’s currently at the luthier being repaired, hopefully done soon. For acoustic practice, I’m using a Takamine 6 string I inherited from friends over a decade ago. It has horrible action, an uncomfortable neck, but it sure is strengthening my fingers and building up my calluses. 🙂
My goal is to keep this up through the year. To get to the point where given a key, I can solo and play along with it comfortably. There’s a long road to this, but now, after 2 months, I’m starting to see progress. I spend an hour playing over a backing track on my SX electric guitar (a yard sale find about a year ago), and it feels… good. Still not the expressiveness I want, but it sounds like music, and feels a bit like music. Progress.
At some point, I’m sure I’ll be able to share some things I’m playing – not yet though. But I’m cautiously hopeful that sometime I’ll be able to stand up in front of folks with some friends, we’ll play a song, and at some point we’ll start a go-around for soloing, someone will nod to me, I’ll kick my pedal, and I’ll solo… in a way that will make me smile, and make others smile, and… hopefully… give me joy.
I first saw the Epson HX-20 back when I was working a computer store in New Jersey in the 80’s. I believe I read some articles about it in Infoworld or something similar, and thought it was awesome. At some point I got to look at one / type a few characters on it, but never got to own one.
This came to me as part of a large equipment sale not far away. It is in EXCELLENT shape, complete with carrying case, power supply, and a couple microscassettes. The printer works fine, everything is in perfect working order.
Released to mass market in 1982, this is widely recognized as the very first laptop computer. It is A4 sized, has decent battery life, a full stroke, full sized keyboard, and many expansion ports.
Original price: $795 ($2040 in 2020 dollars)
CPU: Dual Hitach 6301 CPU at 614khz
Memory: 16k RAM (expandable to 32k)
Display: 4lines at 20 characters
The unit works perfectly, and is a true delight to type on and tinker around with. I will be a great addition to my collection. I’m looking forward to learning more about it!
Back when dinosaurs roamed the earth, I attended a very technical college to start getting my degree in Computer Science. Note, this wasn’t ‘programming’ ‘systems design’ ‘databases’ ‘AI’ or any of that, no, the industry was young enough that just HAVING a computer science degree was notable.
While the college experience didn’t work out well for me, I have a very strong memory of my first semester (back then the college called them trimesters I believe) walking into the computer science building and seeing a glassed in room with a bunch of racked equipment in it. On the front of one of the racks was a brightly colored panel, with a lot of purple and red switches, and many blinking lights. In the corner, it said PDP-11/70, and I thought it was the coolest thing I had ever seen.
Turns out this machine was used in the undergraduate program to teach students Unix. We had a classroom full of DEC GiGI terminals and students would plunk away at shell scripts, learning ‘vi’ and generally making a lot of beeping noises. There were about 16 terminals, which meant that machine, which was approximately 1/5000’th the speed of a modern Core i7 process (MWIPS 0.535 for the 11/70 vs 3124 for the i7) was supporting 16 concurrent users programming away on remote terminals.
Well, life moved on, and while I did build my own DEC minicomputers, I never actually owned an 11/70. They were temperamental, that were designed to be powered up and left running for years. Not exactly a hobbyist machine.
In the last year or two, some folks have been taking advantage of the SIMH project (a hardware simulation environment) to emulate these old machines, and run the original operating systems on them. When I saw that Oscar had put out a kit for the PiDP-11/70, a fully functional PDP-11/70 front panel that mirrors precisely the original machine, I had to have one.
The kit is powered by a Raspberry Pi-4 loaded with the SIMH package anda . bunch of disk images. The system happily runs any number of old DEC operating systems, as well as Unix 2.11BSD, and various other Unix versions. On bootup, you simply select which disk image you want to run, and after a few moments, you’re looking at an operational console happily booting RSX-11MPlus, RSTS, RT-11, BSD Unix, whatever you’d like.
Total build time was somewhere around 7-8 hours. Imaging and setting up the Pi took about 2 hours (mostly downloading packages), and the actual physical build of the front panel took another 6+ hours.
The experience of using the machine is somewhat surreal. In the past, I spent a lot of time learning Unix and then VMS. I also worked on DEC Pro/350’s for a while, which run a modified RSX-11MPlus, so it feel great to be back in that environment again, but I have so much to re-learn.
Having the delightful blinking lights nearby showing activities in realtime is a delightful way to have a visual representation of the inner workings of computers, something we don’t see a lot of in modern systems.
From the humble Atari game system to the high-powered consoles we have today, advancements in technology have truly transformed the way we play games. We are no longer limited to a single-player experience, as gaming has made users more connected than ever before. This has opened up a world of possibilities for the industry that keeps coming out with novel innovations.
Read on for the four trends that we think will change the future of online gaming as we know it.
Since the cryptocurrency boom, blockchain technology has gained mainstream recognition. It has been applied to a variety of things – from ticketing to inventory control. This technology solves many of the current security woes brought about by decentralizing data, storing it in different blocks distributed across a network of computers. This way, it removes the risk of a single point of failure and makes the manipulation of data near impossible. As the technology is improved and adapted, virtual items continue to carry more real-world value. It makes sense that gaming companies have started integrating blockchain technology, with some games built around this specific concept. For instance, the New York Times reports that a CryptoKitties players, a game that deals solely in the collection of virtual kittens, managed to sell one of their CryptoKitties for a whopping $140,000. Future applications could include using this technology to facilitate secure in-game payments and purchases.
Lastly, augmented reality (AR) has seen an uptick in the last couple of years mainly due to the success of Pokémon Go. While it was initially seen as a fad, it quickly became a worldwide phenomenon. Pokémon Go has been downloaded over 800 million times resulting in around $2 billion in revenue. Because of the game’s success, a slew of AR features followed on games such as Harry Potter: Wizards Unite and Minecraft Earth. With the 5G-technology rollout, AR gaming is set to get even bigger thanks to the increased bandwidth and speed gamers will have access to.
It’s no secret I’m a huge fan of Warner Brothers cartoons. My sister and I were basically raised on this stuff, and so much of our cultural reference points (and humor) comes from watching Bugs Bunny when we were growing up.
So, as Halloween approached, I thought it might be cool to recreate an iconic image from the 1952 cartoon “Water Water Every Hare”, where Bugs is taken to a big scary castle on the edge of a waterfall. The castle is inhabited by, naturally, an Evil Scientist, who advertises the fact with a blinking sign on the towers of his castle.
Okay, I’m not really a scientist, I’m an engineer, but I figure I could apply a little artistic license and make a sign like that for my house for Halloween.
I wanted it big enough so I could put it in an upstairs window and have it visible from the pathway. We get a LOT of kids through our community over Halloween, and tons of parents as well (since mostly the parents would get the reference), so it needed to be visible. In order to constrain the glare, I decided to put it in basically a shadowbox configuration. An enclosed box, LED lighting inside, with a cutout pattern on front that would show the text.
First step was to use the laser cutter at the Makerspace to cut out the lettering. As anyone who does stencils will recognize, the second line (“BOO”) would have floating elements in it, and would have to be glued down after the box was made.
I found some old acrylic sheeting that still had one strip of white backing on that, and that made a dandy diffuser, as well as a place to mount the center parts of the lettering.
Next, based on the size of the lettering, I whipped up a box out of some scrap wood, and painted it black. I also painted the letter stencils so the shadowmask wouldn’t show up at night, but the lettering shining through would.
The colored lighting was done with some LED strips and an arduino. The sketch was painfully simple. Just first row on, wait a second, off, wait a half second, second row on, wait a half second, off, then wait a half second and then repeat. The most challenging part was soldering up the strips (I needed 3 rows), and mounting the arduino.
The only thing I had to go ‘buy’ was the backing board. A quick trip to Michaels got me a sheet of the plastic corrugated ‘cardboard’ for $4. This stuff is awesome, and I think I’m going to use it more in future projects. I mounted the LED strips and the arduino to it initially using hot glue, but while that’s the default ‘go to’ for DIY projects, I ended up ziptying the strips to the backing board, and doing the same for the arduino. Since the board is flexible, hot glue just didn’t make sense.
Once everything was screwed together, it was just a matter of putting it in the window and plugging it in. Yay! It worked!
I slightly misjudged the width of the window, so it doesn’t quite have the margins I had hoped, but when it got dark, it looked great. Very happy with the end result!
This past weekend I finally got to let TARS, my Tesla Model 3 Performance, stretch its legs a big and go for some long distance driving. Over 3 days, we covered almost 700 miles, from Boston, MA to Rochester, NY.
This drive is almost entirely interstate, with the absolutely mind numbing stretch of the NY Thruway between Syracuse and Rochester coming to mind as the most tedious part of the trip. I was looking forward to using Autopilot for that bit in particular, and I wasn’t disappointed.
My Model 3 is normally set to charge to 90%, which gets me about 270 miles of range. According to Tesla, this helps preserve the lifetime of the battery. But for short term trips, it’s okay to go into ‘trip mode’ – charge the battery to 100%. That brought my range up to about 307 miles. Golden!
The next step was to plan the trip a bit. With my battery topped up, the trip analyzer said that I could make it to the Utica, NY supercharger in one go. That’s about 270 miles, and I in theory would have 35 miles left when I get there. Now, I treat these estimators with a heavy dose of skepticism. There’s a lot of factors that impact battery consumption – a static analysis would have resulted in a lot of ‘Yeah, but what about…’ questions. However, this estimation was being done by the car, while I was driving it, with active traffic reports being reported in in realtime. It should be pretty accurate, we’ll see!
We rolled out around 2pm on Friday and immediately ran into unexpected traffic (later we learned from some friends that it wasn’t just us – all the routes headed west were problematic). TARS kept updating the route onto more and more secondary roads, to the point where I was expecting us to be routed through someone’s garage and down their garden paths. Hopefully I could avoid any empty swimming pools.
Finally, we got past the traffic and on the open road. The car settled into the traffic fine, and I was able to enable autopilot for a large part of the rest of the trip.
There’s an awful lot of jawing going on about the Tesla Autopilot. It’s not full self driving (FSD), no. It’s also not ‘just adaptive cruise control’ (as I’ve heard others yammer). It’s somewhere in between. On an open highway, without much traffic, it’s dreamy. Lane changes, slowing down / speeding up according to traffic changes, dealing with people merging in or passing, it works well. The car software is updated often – anywhere from once a week to every few weeks. And each time a new version comes down, the autopilot gets better, smoother, and less janky.
Here’s a good example. When I received my car in May, it was just after the ‘automatically change lanes’ function was enabled. And it was sketchy AF. Yes, it would signal, change lanes, and continue. But the signal ranges were all goofy, and if there was someone anywhere near your blindspot, the car would sort of ‘stall’ – leaving the blinker on, waiting for the other car to move. If they backed off to let you in (like all nice New England drivers do, right?), the autopilot wouldn’t pick up on the situation change fast enough, so would just sit there with the blinker on. Naturally, the other driver would speed up thinking I wasn’t changing lanes, and then Autopilot would decide there was a threat, and ‘phantom brake’ or jog back into lane. it was unnerving.
With the current version (v32.12.1 – one patch level beyond the v10 release), this process is FAR smoother. I was comfortable letting the car decide when to change lanes to get around slower traffic, or move over to let other cars by.
Interstate changes and ramps were still a little off. When the car does not have clear lines on the road on ramps (which tend to be wider than normal highway lanes), it tends to disconcertingly head toward the outside of the ramp until it’s close to a line, then sort of jog back. It’s jarring and uncomfortable, but it will do it. I let TARS make 2-3 highway changes for me, keeping my hands and brake-foot ready for a sudden takeover.
First Recharging Stop
Eventually we made it to Utica, and pulled into the charging station. At this point, the display was showing we had about 20 miles of battery range left. I had been watching the numbers the entire drive, and even with the traffic, rain, etc, the numbers really didn’t change much. The computer had the advantage of having access to traffic, weather, temperature, and route information, as well as how my batteries were behaving. It didn’t get it wrong.
We jacked into the supercharger and got the message “20 minutes until you can continue your trip” – Huh! 4+ hours of driving, and a recharge in 20 minutes? I’m good with that. Lets grab dinner.
So we walked to the local food joint and had a quick meal while the car recharged.
Getting back in, we were at something like 240 miles of range, plenty of electrons to get us the last 2 hours to Rochester.
We ended up going to our friends house first, then to the hotel, which left us with about 90 miles of range. Plenty for the next day, but we should top it up at some point.
On Saturday, we topped up the car with a very fast stop at the local supercharger (20m on the charger), which got us back up to about 200 miles. This is where I start having some questions.
It looks like not all superchargers are the same. Some have very good high speed charging (500+ miles per hour charging speed), others are lower. It’s not because there’s more cars at the charging station or anything, the level of power coming from each station just seems to vary. This is disconcerting, because when you’re trip planning, some stations may be able to charge your car up to full trip-level charge in 40 minutes, others may take an hour and change. Now, the charging ‘curve’ for a Tesla isn’t flat. To go from 0-75% charge can take as long as it takes to go from 75% to 100%. If you’re doing long distance driving, the time it takes to top up gets important. The station near the hotel was not charging as fast as the one in Utica. That was concerning, because we should be able to fill up before we drove home on Sunday. Timing would be important.
At the end of weekend, we did the happy party trick of showing off Enhanced Summon in a crowded private parking lot (there were half a dozen cars in our friends driveway, and rock walls all around. I walked a hundred feet away and did a “HOLD MY BEER” by summoning TARS to me. It did it BEAUTIFULLY. The summon feature has improved greatly in two or three weeks it’s been out. Very smooth, and doing exactly what a human would have done to back up, move the car forward and back 2-3 times to line it up with the exit, then roll over to where I stood.
It’s a great trick to impress your friends with. I asked our host “So, getting a Tesla now?” and he, a normally very conservative skeptical person, answered “I hadn’t thought about it before, but now I’m seriously considering it. I’m very impressed.”
We headed out to the charging station I had used on Saturday, and had the same rate problem I saw before. So it wasn’t load or anything, it was just that this station sucked. We went for a walk in the local mall, and decided to head out. The mapping system set our next recharge in Lee, MA, about 270 miles away. We should arrive with 20-30 miles of charge left. So off we went.
The drive back was uneventful, with autopilot doing it’s thing for most of the drive. Oddly, my biggest issue was I rest my hand on the steering wheel giving it a little ‘tension’ to let the car know I’m there. After 20 minutes of leaving my hand in one spot, it would get tired and sweaty, and I had to switch hands. Talk about first world problems!
We got to Lee and plugged in, and YAY! Plenty of high speed charging! What a relief. We were able to top up the battery enough to get home in under 15 minutes, and we got home to a dog that was extremely happy to see us after such a long time away (Yes, we had people taking care of her, don’t be like that. But she did miss us).
All in all, the road trip was everything I expected it to be. Smooth, fast, comfortable, and best of all, 100% electric. Assuming our chargers were getting elecricity from standard sources, we produced 1/3rd as much carbon as we would have in a normal gas car. I personally buy my electricity from a wind farm, so at least 1/3 of the trip was from renewables, so that reduced our footprint even further.
Someone asked me from a cost perspective, was it cheaper driving an all electric car? I found an article that summed it up like this:
The long-range version of the Model 3 has a 75 kWh battery pack with a 310 mile range. If we still assume the average national electric pricing of 13 cents per kWh and a charging efficiency of 85%, then a full charge will cost $11.47. This is $3.70 per 100 miles of mixed city and freeway driving, or 3.7 cents per mile. This is almost 80% less than the cost per mile to drive the most popular gas-powered cars, which is approximately 20 cents per mile.
This fits my back of the envelope fiddling. I looked at my bill, and the entire charging costs from Sunday’s drive (about 370 miles) was $11.47. So not only was it not putting out any CO2, it was far far less expensive to operate than a traditional car.
I can easily see a future where more and more of these trips are automated, and my input into operating the car will be needed less and less. We’re not there yet, and we won’t be for I’m guessing another 3-5 years. But the progress is absolutely there, and I welcome it.
Woodworking. Okay, great, another rabbit hole to go down, right? Well, sorta. Over the years I’ve learned to knock things together, how to saw, hammer, screw, paint, and assemble things out of wood, but I never really understood finishing. How to shape something creatively and come up with something beautiful at the end.
About a year ago I took a class up at Makeit Labs on the wood lathe. Lathes have always been fascinating to me, like potters wheels for wood. Take a primal material, spin it, and (in the case of a lathe) by removing material, shape it into something beautiful and smooth.
The class was great, and I learned the basics of turning. How to use a gouge, how to set up the spindles, and probably most importantly, what not to do to protect both myself and the equipment. I did a little turning after that and made a small parts holder for my work bench, but life stuff got in the way, and I didn’t do much else for a while.
A few weeks ago things were shifting back to slight normalcy in my life, and I found myself with a few hours of free time up at the lab. When I first took the lathe course, I bought a box of sugar maple blanks, about 4″ wide and 5″ long. Maple is hard wood, but can be turned pretty easily. I decided to try and make a type of cup I’d like to use for hand lathered shaving cream. So it needed to be wide enough for the brush and also relatively waterproof. (Turns out after I did the shaping, the size I was using was too small, and making wood ‘waterproof’ is actually pretty hard, so this ended up just being a sample / test piece.)
The initial work took about 2 hours to get the shape down to what I wanted. It’s funny. Woodworkers learn this pretty fast, but it takes a while to sink in. The turning / shaping part of the process is the most rewarding and creative, but is the easiest / shortest part of the entire process. I could carve wood like this for hours, but I’d end up with a bunch of carved unfinished pieces. That’s not what I wanted to learn this time around, I wanted to take it to completion. So after the shaping was done, I took the piece home to start the finishing process
First of all, it needed to be stained. Some Minwax cherry stain was acquired. I took a sheet of 220 grit sandpaper to the entire piece, and sanded it smooth inside and out. Learning how to sand the inside of a cup without gouging it is a bit of a challenge, particularly when the opening is only 3″ across or so, but I was able to get it pretty smooth.
After putting on a set of latex gloves (this part I knew. Stain stains EVERYTHING – including hands!), I brushed on on the first stain, and the color jumped right out at me. Hey, I can see the grain! The instructions said I should smooth the stain on, let it sit for 15-20 minutes, then wipe off the excess. I did that, and the result was… good. Not earthshattering, but it was a mark above just a raw wood piece. I began to see problems working with a piece that was this shape… the stain tends to settle on places that were more horizontal, so the base had a darker look than the sides. I resolved on the next layer to make sure the areas that had less color would get more coverage.
After a light sanding to help remove the excess on the flat areas, I stained it again, and the color was better, but still relatively dull. I mean, yeah, I can hear folks going “Duh, you’re not done yet” but I was hoping for a little glow from the coloring. Nope, not quite yet.
The last step was to put a few layers of polyurethane on. Now, this is a tricky topic, and I suspect major fistfights have broken out about how to this properly, what materials to use, etc. As this was my first piece, and I’m hoping to make things more water resistant in the future, I chose an oil-based clear poly coat. This should make it ‘okay’ for this to get wet, but I wouldn’t want for it to be holding buckets of water on a regular basis.
Poly cures slow, so I put on a single coat, waited until it had cured (about a day), sanded it with 220, wiped it clean, and put another coat on. The result is… good. I like it. It has a healthy glow and shine to it, and I can say “See this? I made this.”
So now what? I’m going to check around about how to do final polish / finish. Do I sand and buff the poly coat one more time? I think yes, but I need to check. Even if I stop now, I can put this on my shelf and go “I like this. I made it.”
I’ve since picked up a lathe I can use at home to do my own turning, so the next project hopefully will be entirely homegrown. Stay tuned!
The past 6 months have been quite the whirlwind. I’m sure I don’t need to do the rundown, most of ya’ll know what’s been going on, but I have to say, today is one of the first days in a long time where I feel things are settling back to normalcy.
I’m sitting in my living room listening to piano music on Spotify, my dog is happily snoozing on the couch next to me, my family is out of the house – one is at school, the other is out visiting a friend. The summer weather heat has broken and I’m able to sit in my space, doing my job, and just… relax.
I finally got it. I got the robotic, electric, high performance car of my dreams. Sleek, fast, geeky as all get out, tremendous range – it’s everything a nerd would want in a car.
But it’s not perfect.
People have been coming to me pretty regularly and saying “So, how do you like your Tesla?” – and I answer truthfully. “I love it. It’s amazing. It’s my robotic space car. It’s nerdy and stupendously fast. But it’s not without its faults.” At this point their eyes light up and they get excited. “Yeah? Like what?!?”
The automotive press has not been kind to Tesla. With a strongly outspoken CEO in Elon Musk, it’s lofty goal of bringing affordable, exciting electric cars to the masses, and the base challenge of pushing against an industry selling a few hundred billion dollars worth of cars every year, it hasn’t been easy for them to break into the market and succeed. But succeed they have, pretty much jumpstarting the performance / luxury electric car market singlehandedly.
But there are problems. The car is hardly perfect. I’d like to run down the flaws and issues as I see them…
Tesla the company is relatively new in the automotive industry. Founded in 2003 right after the dot com bubble burst, they spent some years understanding what it takes to build a new kind of car from the ground up, without carrying all the folderol that the big auto manufacturers have. The Roadster came out in 2008, and the Model S 4 years later in 2012. In that time, the focus had to be on technology, manufacturing, and production.
What they didn’t have a chance to focus on was the customer end of things.
Dealing with Tesla can be an infuriating process. Because they don’t have a ‘dealer’ model similar to current car manufacturers, buying a Tesla is not far from ordering a laptop from Apple. You got to the website, choose your option, click ‘Buy’, and a car will be available… sometime.
It’s this ‘sometime’ can be problematic. Without a salesperson to regularly work with, the delivery process is extremely oblique. There is a nice website that will tell you the status on your car, but it’s not particularly informative, showing things like “We’re putting together your paperwork” for WEEKS until it suddenly changes to “Your car will be available for pickup in 3 days at such and such a location.” Thanks guys.
The Delivery Process
Okay, so now you have a delivery date. What happens at the delivery is relatively normal. You show up at the ‘delivery center’, 1-2 folks walk you through the dos and donts of the car, you sign a bunch of papers, and you drive off in the car. This actually went fine, the only drawback is the people there are complete strangers. No one knew me or anything about my excitement or interest or history. They were basically just like a refrigerator installer. “Here’s yer machine, bud. Seeya.”
I have a Model 3 Performance, which has some nice trim changes, but in general, the Model 3 is BORING. It’s a 4 door sedan. I suppose this is better than some of the more radical car designs floating around (Have you seen the new Civics and Prius’s? Yikes.) But on the other hand, if I’m getting a fairly expensive car, I wouldn’t mind if it turned heads just a little. People who know Teslas will go “Hey! Look! A Tesla!” but for the most part, the Model 3 just blends in with the other shiny sedans out there.
Having said that, there are some Issues – well known, easy to work around, and possibly even understandable for a ‘first generation’ run of this model, but they’re still there:
The delivery person warned us of this, but I did it before he even told me. There’s a nice little hatch that opens and closes over the charging port. You can unlock this hatch from the mobile app or from inside the car, or by touching the bottom of it when you want to plug in the cable. BUT. You should never try to close it by hand. Nope nope. Don’t push on the top of it or move the door, that can break it.
The storage space under the front hood (where an ICE car would have an engine) is referred to as the ‘Frunk’. Apparently, this thing is delicate as heck. The delivery guy went out of his way to tell me to never slam it, nor close it with one hand. Gently set the hood down onto the latch, and then push down with both hands on either side of the latch. This seems like an obvious workaround to a design error, but it’s not something a normal person would think to do.
Much has been said about trim and panel fit. Sometimes the cars don’t fit together cleanly and properly. This was a real problem in the first runs of the Model 3, but far less so in later ones. I received mine in the spring of 2019, and haven’t noticed any particular gaps or bends or points where things aren’t coming together. Having said that, there has been a persistent whistling noise coming from the drivers side mirror. If I stick my hand out while driving, I can make that sound stop, but it’s obvious there’s some gap in the trim that’s causing air to whistle through it.
The interior of the car is beautifully simplistic. Comfortable, laid out well, lit well, and easily the most comfortable car I’ve ever owned. The expansive glass roof, plenty of headroom, very adjustable and supportive seats, and the well articulated steering wheel all help make the car extremely comfortable.
But, this article isn’t “everything that’s awesome” – lets look at some of the flaws.
I absolutely detest the door lock mechanism. For those who have not been in a Model 3, there isn’t an actual ‘door latch’ that you pull to open the door. There’s a button. You touch the button, the window slides down about an inch, and the door unlatches – and then you push it open. There’s a sort of emergency latch that you can pull up, but the Tesla rep warned me never to use it, as it might damage the door. This just seems like poor design or an afterthought. It’s taken some time to get used to the ‘push button to open the door’ methodology – I almost never get confused now, but it’s really a very bad choice of design.
The center console is a mess. There’s several chambers, each quite deep and having a different ‘lift’ or ’tilt’ mechanism. They’re also cavernously deep, so putting something in them is akin to dropping the one ring into Mt Doom. You will likely not get it back easily.
No drink holders in the back? Well, they are sort of there, but they’re in the center console between the back seats. That’s… sort of weird, particularly if people are sitting 3 across.
It took looking up in the manual to figure out where the emergency 4 way blinker lights are. I’ll leave it as an exercise for the reader to try and find the control next time they’re in a Model 3. We couldn’t find it until we looked it up in the manual. This is an EMERGENCY BLINKER button. It should be trivial to locate. It isn’t.
Why doesn’t the front drink holder have removable silicon liners? Those things get DIRTY. Even inexpensive little toyotas and kias have silicone liners for the cup holders.
Okay, lets start talking about the controls. This section isn’t about the software that runs the center display / functions of the car, this is basic control layout and usage.
The Model 3 has a very simplified set of operator controls. The steering wheel (obviously) two foot pedals, two control stalks (one on each side), and two thumwheel / joysticks. And the horn. That’s it. Everything else is done via the touchscreen. But lets look at those controls.
The stalks are useful and well placed, as are the thumbwheels. I never lose track of where they are. And there were some logical decisions made about what each set does. The left thumbwheel is ONLY audio controls (volume up/down, next/previous track, pause and unpause). The right thumbwheel is for quick commands to the autopilot / cruise control system. Pretty easy to work with.
The stalks are more complicated, because they service multiple purposes. The left one is your turn blinker, obviously. It also controls your high and low beams for the headlights, as well as a ‘quick touch’ to turn the windshield wipers on and off (assuming the auto wiper system doesn’t work).
The right stalk is sort of like your gear shift. You control what ‘gear’ you’re in (drive, reverse, park), as well as the state of the autopilot system. I haven’t figured out a lot of the wiggle functions on that stalk, other than engage autopilot and ‘go into drive’.
Sounds basic, so what’s are the issues? Well, there’s a bunch:
First, the mechanism for turning on and off turn signals is confusing. A light push on the left stalk, up or down, will blink the turn signals 3 times. If you hold the stalk, they’ll keep blinking until you release it. There’s a ‘secondary’ level of push though, that means “turn the turn signal on until… something tells them to stop.” – this part is the confusing one. The turn signals will stop blinking if the car thinks you’ve completed a turn, or… you signal some other way. How to turn off a turn signal seems to involve some invocation I still haven’t worked out. I find myself signaling in the opposite direction sometimes, or just wiggling the stalk around until the signals stop. This is hardly safe communication with other drives. On a normal car, the turn signal stalk locks into position until it either is automatically returned to a neutral spot, or you force it back to the center. The Tesla turn stalk doesn’t do that. It is always in the ‘neutral’ position whether you’re signalling or not. This is confusing.
Second, you can only sort of control your wipers via the end button push. A quick push will wipe your wipers once, and a longer push will turn on the spritzers. The wipers are normally controlled via the center touchscreen (with intermittency and automatic settings controlled there). But there’s numerous times i find the ‘automatic wipers’ don’t really keep the windshield clear enough, so i find myself pushing the button a lot. Or navigating the touchscreen to turn the wipers on and off faster or slower. You don’t want to be fiddling with the touchscreen while driving. This is not a very good setup.
High and low beam headlights work as you’d expect, though the ‘automatic’ high beams is gimmicky and works poorly. More on that in the Software section below.
Oddly, the right stalk is mostly okay. the gear position mechanism makes sense, and the ‘double press’ to engage autopilot is intuitive and works well.
I’m going to lump a couple topics into this section, but first some preamble.
So much of what makes a Tesla a remarkable vehicle is the decision to base as much of it’s functionality as possible around software. This is why there’s only one display system (the touch screen), and virtually every function is managed and displayed through this interface. It makes it easy to change, easy to upgrade, and easy to tune. All the ‘smarts’ of the car (it’s sensors, battery management, and yes, even the power train) are controlled via software. Some of that software is visible to the operator directly, but a lot of is internal. The operator doesn’t see the battery management, the heating / cooling systems, the adaptive drive for the motors, etc. The operator mostly sees the interface on the display. So lets focus on that.
The Tesla Model 3 has one large 15″ LCD touchscreen in the middle of the dash. There are no other display systems in the car. No turn signals, no idiot lights, no dashboard. Just this display. This ‘one screen to rule them all’ makes the Tesla much easier to upgrade and modify. In a traditional car, you can’t move the heater control from one place to another because, after 6 months of use, you realize the original placement was poor. But on a single screen like this, it’s a simple software change to rearrange controls. This has disadvantages as well. The center location of the display is awkward for the standard driver who expects basic operational information to be directly in front of them. The speedometer is in the upper left corner of the screen, as are basic status lights like blinkers, hi/lobeams, and what gear you’re in. All other controls and information is located at different points of the screen ,and sometimes that info may be hidden or on a different tab. This absolutely takes time to get used to, but it means improvements can be made via software. By comparison, my Chevy Volt had the WORST design ever for it’s center console, with horribly placed buttons that were impossible to understand. The software interface on the touch screen was mediocre at best, and over the 3.5 years I had the car, they made absolutely zero UI improvements to that display, when any number of changes could have been made – just not to the button layout.
But enough background. Given this amazing technology, the interface and tools must be awesome and perfect, right? Oh hell no. Lets investigate…
There’s a system in the Tesla that allows the hi/lo beams for the headlights to automatically adjust based on oncoming traffic and other cars. On the surface, this seems pretty straightforward, and it works relatively well. Until it doesn’t. Hi/Lo beams are also a mechanism most drivers use to communicate with other drivers. “Your lights are off” “Something dangerous is ahead” “I’m a jerk”. The Tesla software will turn the hibeams on and off depending purely on distance to another car in front of it (if it sees it), and if another car is coming towards you. That’s it. On the highway, the highbeams can flicker up and down automatically several times in a minute depending on how far behind another car you are. This is irritating as heck for other drivers. While a nifty gimmick, I disabled it.
The windshield wiper automatic system is supposed to turn on the wipers when it starts raining, turn them to ‘fast’ when needed, and off when things are dry again. I find myself many times going “Why aren’t my wipers on?” The system is very cautious about when to turn them on. Once they’re on, they’re fine, and will turn themselves off after the rain stops, but I do find myself hitting the ‘wipe now’ button regularly because the automatic system hasn’t yet figured out the window is wet.
For some, this is it. The holy grail of the Tesla. The much vaunted ability for the car to drive itself. The model 3 has 8 external cameras that can ‘see’ to a distance of about 250meters. In addition to the cameras, there’s also a front facing radar that gives very accurate distance measurements to the computer. These systems together provide the autopilot computer in the car enough information for the car to drive itself. It can see obstacles, react to changing circumstances and environments, and navigate it’s way in relatively complex situations. It couples that information with maps that are constantly updated with traffic and construction changes. The car’s GPS will locate you on the map (though the Tesla won’t use GPS for very high detail information. You don’t want to depend on GPS for autopilot, then go into a tunnel, for example).
So, given all this technology, is it actually dependable as a self-driving system?
The autopilot has many many problems. It’s definitely not ready for prime time. While it is an absolute technological marvel, it is nowhere near the level needed for full autonomy. Even in the best possible driving situations for autonomous navigation (a mostly open highway), the system makes many many errors in judgement. Most of the time those errors are not threatening or dangerous, they’re just uncomfortable or irritating. A few examples:
The autopilot can change lanes as needed for faster / slower traffic or when approaching an exit. If there’s any form of traffic in the way (someone coming up quickly behind you, or a crowded lane), it’s handling of the lane change is infuriating. Not for me the driver, but mostly for other people on the road. It takes far far too long to make the decision to change lanes – and by the time it does, the ‘gap’ it was shooting for doesn’t exist anymore, so the car can swerve back into its original lane. Again, not particularly dangerous for me the driver, but irritating and alarming for people around us.
There are regular ‘phantom braking’ problems. You could be going along normally, and suddenly the car will ‘brake’ abruptly for no apparent reason. A moment later it’ll resume normal speed. This is jarring. I’m sure it had a very good reason to do that, but there’s no indication to the driver or passengers what just happened.
Autopilot HATES wide lanes. Onramps that don’t have middle dividing lines, or secondary roads that aren’t perfectly sized – the autopilot will ‘hunt’ from one side to another trying to guess which is the proper side of the road to be on. Ung.
The ‘navigate on autopilot’ feature which is supposed to allow the car to happily change from one highway to another using ramps without driver intervention gets easily confused on anything less than perfect interchanges. If the lane markings aren’t crystal clear and well sized, the car will jump around trying to determine the ‘best’ path on the ramps – and will frequently guess wrong.
The system is not ready. Having said that, Tesla is doing the right thing to get it there. Their software is constantly ‘learning’ how to drive properly – every Tesla on the road is collecting data on how people handle these weird road conditions, and that goes into the neural network that the navigation computer uses. And each update, it gets a little better. But I can’t see a driverless Tesla, or a ‘door to door automated driving’ Tesla on the road in the next 5 years.
So we’ve talked about basic software tools and functions in the car. In addition to those things, there’s some stuff that’s just plain goofy and fun to have. Since the Model 3 is basically a computer with a touch screen attached to a car, there’s some silly stuff you can do.
My question is, is this stuff really adding any value?
For instance. You can play games on the display. That’s sort of fun, and the display is good and uses the existing car controls to play the game. But that means you can only play in park. And from the drivers seat. This seems more of a ‘Hey kids, look what my car can do, neener!’ feature than something I can use as a selling point for the car.
Yeah, I have the Performance version of the model 3. That means the extra motor, the low profile wheels, the painted calipers, the whole shebang. Those extra options added another 25% to the base price of the car. What do I get for that? Well, to start there’s that neck-snapping 0-60 in 3.3 seconds acceleration. Driving a car with this much power, with an always-available 450HP and 470 ft-lbs of torque is intoxicating. It changes how you handle traffic, navigation, everything. That power is ALWAYS there. No downshifting, no revving / turbo spool up. This car is the modern day equivalent of Neal Stephenson’s Deliverator from Snow Crash:
“The Deliverator’s car has enough potential energy packed into its batteries to fire a pound of bacon into the asteroid Belt. Unlike a bimbo box or a Burb beater, the Deliverator’s car unloads that power through gaping, gleaming, polished sphincters. When the Deliverator puts the hammer down, shit happens. You want to talk contact patches? Your car’s tires have tiny contact patches, talk to the the asphalt in four places the size of your tongue. The Deliverator’s car has big sticky tires with contact patches the size of a fat lady’s thighs. The Deliverator is in touch with the road, starts like a bad day, stops on a peseta.”
But, the performance version has some drawbacks. The cost? I’m not sure if it’s worth it. Is it really necessary to have THAT much power at your beck and call at any minute? I don’t think so. The only time I’ve really used it is to impress people I take on test drives. That’s not worth the money.
But let’s also talk about those low profile wheels. The short version? They suck. They’re fragile as hell, and they are NOT covered under warranty. Yes, everyone ‘knows’ that low profile wheels are the worst thing to happen to cars since they added ‘tiptronic shifting’ to every hyundai on the planet, but at $750 a pop for those wheels, hitting a pothole gets real expensive, real fast. Ask me how I know.
A model 3 AWD Long Range will get you 0-60 in 4.5 seconds, for $12k less. Do yourself a favor. Unless you’re dripping money, if you want something that’s still faster than most cars out there, just get that.
So where does that leave me? Do I like my car? Yes. Am I excited everytime I get in it and drive? Definitely. Am I proud that I am using a vehicle that emits absolutely zero carbon dioxide, and I’m powering from energy I buy from wind farms and solar? Absolutely. Do I think this is the future of cars in the world? No question.
Is the car perfect? Absolutely not. Not even close.
But it is, by far, in my opinion, the best electric vehicle on the market today.
