Short of full-blown self-driving, I think it would be great if Carplay tied into OBD 3 or whatever the current iteration is. Modern cars are so sophisticated that it is almost impossible to diagnose a problem. Likewise, some crucial systems can be failing with no warning. Why not give the infotainment system access to the OBD bus? Instead of a cryptic engine light coming on, Use the full power of that interface to describe the problem, let the driver learn in more depth about what is going wrong, offer to contact nearby dealers, and make an appointment to fix it, or access an online service manual. Link to YouTube videos on how to repair it. Technology can demystify itself and empower drivers. I drove a Lotus Europa for 14 years. I knew every nut and bolt on the car. No matter what happened, I could fix it. Those of you who have mastered your cars know how wonderful it was to have that power. Until we can get to cars that drive and repair themselves, I think this is a great stopgap. If anyone takes this idea and runs with it, great, just give me one of your systems and we're good.

The main reason is because there are fewer, MUCH fewer, moving parts in an electric car. I would hazard a guess that probably 50-80% of the "faults" in OBD don't exist in electric cars (like oxygen sensor, knock sensor, airflow meter, coolant thermostat, etc). The trivial ones, of course, would still exist (like left front turn signal bulb out, etc).

Until we can get to cars that drive and repair themselves, I think this is a great stopgap. If anyone takes this idea and runs with it, great, just give me one of your systems and we're good. I could see being a OBD system reader, and having much more info. That's pretty much the difference between the various levels of readers now, with Scotty always going on and on about his $5k or $2k OBD tool. The problems are complexity, and over integration. Those can both be fine if done well, and very reliable. But in scanning the consumer reports data, both Toyota and Ford Trucks have times where most areas of the vehicles are solid, but they had some reliability issues with the infotainment system or other electronics, which gave it a bad mark. As the screen and related become more and more important, it changes from just a radio not working, to a major functionality hit. And the costs to fix it go up too. I'd like to see more of the "see dealer" settings to be manageable for the end user. We were able to put in a new key fob, though it was a 20-30 step process (think an old-school Nintendo cheat code: Up Down Up Down Left Right Left Right A B A B Start). But many of the things, like modifying the default unlock to unlock everything instead of taking a double push, it wants you to go to the dealer. And yea, for $100 they can set that for you. OTOH, it's all the upsale, and some easy steps are obscured just for the upsale. Our Sienna has daytime running lights, but while the dealer will charge you $100-$200 to add it to ones that don't have it, they were prewired that way and just need a jumper added in the fuse box. 1 minute tweak. I think there are multiple cool features or tie-ins that could occur. But for reliability and safety, it's probably best to keep some of these things separate, even if it's just as a different video-in link to the screen but still needing a replaceable screen. ie for those that want NAV, it can be a different link in, just as the backup cam is. The problem is tying it all in to not be clunky, but the reliability and serviceability should make it worth it to figure that out. It's the opposite of putting the whole system on a chip, at least until that whole system becomes solid enough that it's not a worry anymore. Then putting it all together, and the benefits that would give, comes into play.

The trivial ones, of course, would still exist (like left front turn signal bulb out, etc). Can someone with more knowledge than me explain why electric motors fail? We recently had the motor on our Kitchen Aide Stand Mixer fail, losing it's magic smoke and everything. When replacing it, there were melted plastic bits in there. I think it was just heat when kneading dough, and jumping the temperature fuse got it working as a test with a light lode, before the new motor arrived. Likewise we have gone through a few electric pumps on a waterfall. And a coffee grinder motor. And a snowblower starter. My theory is that it's just mostly heat, though it could also be vibration, creating some shorts between the initially insulated wire wraps. As this happens, you get hot spots, unbalancing, and generally providing less force or requiring more energy to make the same force. The pump also has the probably of being submerged and potentially having water related issues, but a tear-down doesn't really look like most of them failed that way. Is this somewhat right? Like a duty-cycle on a welder, it's about how much power it can put out for how long, and going above that can cause problems? I would expect with a car there could be more temperature sensors and limiters, while mostly going old-school VW air cooling, but then you are getting into more things that could fail while still having potential heat issues in certain situations. Over-engineering should help. But like a traditional car, juicing it for everything it's got, like consistently using Launch or Ludicrous mode, it likely to wear it out. What do you think? I'm just guessing based on educated guesses. Is really the main electric motor wear due to heat, or does a quality motor also have vibration issues slowly wearing away the insulation to cause failure?

I think that the days of the do-it-yourself car owner are rapidly disappearing. The lawyers will make sure of that. There will be too much liability with autonomous cars as it is without the idea that there may be someone touching something that they shouldn’t have touched that could cause an injury. I read many years ago that Rolls Royce had started locking the hood (boot) on their cars to prevent anyone other than a RR technician from touching anything. I know that I wouldn’t want to drive any autonomous car that I had messed with.

I read many years ago that Rolls Royce had started locking the hood (boot) on their cars to prevent anyone other than a RR technician from touching anything. I know that I wouldn’t want to drive any autonomous car that I had messed with. It depends on what you want to repair, replace, or upgrade. Sure, with no ICE, and thinking about what I've done over a few cars over the past 13 years, I wouldn't be changing the oil, the air filter, the fuel filter, spark plugs, wires, distributor cap and rotor, shifter pad, oxygen sensors, or the alternator. And possibly not the battery. But there would still be shocks/struts/springs, CV joints, door/rocker panel/mirror (friend's car), cabin filter, brake pads and rotors, belts and hoses, lights, relays, fuses, speakers, rear door struts, slider hinge, steering fluid replacement and boot, transmission fluid replacement, and wheel bearings. Wow, that's a list, and mostly all on generally reliable Toyotas. I've enjoyed learnings about them, and it looks like roughly half of the stuff I've done would still be needed. The engine is important, but there are still a lot of parts on a vehicle to wear out in the first 200k or so. Replacing a sensor on an autonomous car shouldn't be a big deal. But I remember a couple friends 25 years ago saying they'd never touch the brakes on a car, whereas it's one of the easiest things I've learned to do. It's not 100% fail safe, but as long as you get the parts back in, and pump the brakes a little before freaking out, it's pretty simple.

Great day for the market, back near ATHs. Mediocre day for AAPL, inside yesterday’s range.
When was the last time the market was at all time highs and AAPL was down 15%?

Who *are* these people? GME opened this morning at $44.70, only to finish the day at $91.71, up 103.94% with a volume of almost 42 million shares traded compared to the average 34 million. Then it continued up after-hours to $166.40, +81.44%...so up about 272% so far, just for today. I saw a GameStop story on the news about a week ago where the reporter Zoomed with his teenage grandson about GME and the grandson informed him that he, the grandson, had bought one share of stock at $293/share with plans to sell it at $1,000/share. Since the grandson's purchase, however, the stock share price had dropped considerably, so the grandson had changed his original plans...and now planned to sell at $400/share. 😂 The after-hours price has begun to drop from $166, so it may finish up *only* about 104% today.

SMH View AttachmentThe video on this article has one of them. Not a great video, but in this case it's a person who took some risks, made some money, but expects to keep making money and even had long term aspirations about GME. Good for him. (even if I don't share his feelings for GME) www.cnn.com/2021/02/24/investing/gamestop-shares-climbing-again/index.htmlThere's all sorts of investors, with many different goals, in just about anything. Even though I may not agree with investing in GME, many have done well. For those that didn't, or that stay invested even if the stock falls, they learn something. Lots of people made learning mistakes in past frothy times, thinking of all the employee stock option rich people, who transferred it over into shares only to have the stock plummet and thus owe more taxes than it was worth. That sort of thing is always tough. Given that I have occasionally had huge tax year gains, but have also had a couple huge tax year losses, I'd like to scoff at them or even try to pass along some hard earned knowledge. But some things have to be learned individually to fully comprehend, and their "schooling" has been even more condensed. That $300k he now speaks of probably started at $20-40k, went to 700k or more, and dropped to $150k before this partial recovery. Holding through that, especially in just a month's time, takes some perseverance or stubbornness. How it plays out in the longer run normally decides which term is used, though I feel I was likely being more stubborn than not at times with AAPL. The jump today, which was only in the last hour and a half of trading, is pretty amazing to me. Will it last? The cynic in me, that tries to understand the psychology around some of these moves, thinks it's probably just a short term blip by some big cash to juice the little guys. The pump is primed, like a high lottery ticket pot, and it wouldn't take too much for the people watching it to dump a little more money on their stock pick lottery ticket. It just seems unlikely that it would be based on the CFO stepping down, but ~24hrs later. It's great that GME at least realizes that they need to make the move over from bricks to online. Apparently Frys didn't manage that in a timely manner, and is just throwing in the towel.

Thanks Dave! While technical in nature beyond what I can fully retain in one watching (shaped magnets added to control the eddy currents in offsetting manners to minimize low torque areas) it's interesting to hear about continued improvements on EV motors. It might not matter much on a little bathroom fan, but on cars built at scale, even just a couple added percent helps. I didn't know that heat was a/the killer of permanent magnets. The benefit of a segmented magnet was interesting too. I want things to last. The 4runners I find at the junk yard have up to 350k on them, with the least at 198k, and often it's a crash that takes it out. Move onto different manufacturers, and you often see lower miles, newer vehicles, and some without accidents. It's a strange place that I don't go to often, but it's also a bit like an archeological dig, learning or guessing at the past.

When I was growing up my father and I would visit the junk yard and find a car and drag it home, we would do the necessary repairs and it would become the families extra car. For some reason my father was always drawn to the Studebaker’s and Nash’s. I thought that the Chevys and Fords with the big V8’s would have been a better choice which may explain the choices he made. Life was simpler then. Strange that the spell check doesn’t recognize the name “Studebaker”.
