EVs are not complicated. Modern carmakers might make them complicated, and you're well within your right to avoid those, but in general electronic propulsion is pretty simple. The problem is car manufacturing is a very expensive industry that's extremely difficult to disrupt, so incumbents aren't really worried about staying ahead of hungry competitors. Go look at small-scale PEVs - ebikes, scooters, unicycles, etc.…

You're right that they shouldn't be, and don't have to be. That doesn't mean that the ones that actually exist in the automotive world actually are, and it's rather egregious to claim that they aren't. Doubly so when you try to substantiate t…

If you read my comment you'll note that I acknowledge that building cars is complicated. I don't think the electric powertrain is complicated (at least, not compared to the explosion-propelled mechanical marvels of legacy ICE - maybe that's because I'm an EE and have a much harder time imagining how a modern ICE works as reliably as it does :D)

It's like the S60, VW W12, old V12 Continentals, etc. If it's expensive to maintain no one wants to buy it off you so you get hit with massive depreciation costs. You can get a 20y/o 'no issues' 500+hp V12 Continental for 10k where I'm at. They've had a brutal cost/year and cost/mile.

Huh? S60? Can you clarify? I've driven a 2003 Volvo S60 (plain 5 cylinder, no turbo), which matches your 20 years - and most diy repairs were quite straightforward. I suppose you're talking about some Mercedes or other brand I'm less familiar with?

Oops, meant the S85 of the E60 BMW M5. Where I'm from we call it S60 since it's the S engine. Forgot it's not a real thing...

Wait until you see a picture of a clutch replacement on an R1200... this should probably have a NSFW tag attached: https://www.reddit.com/r/motorcycle/comments/1he20rk/r_1200_...

Thanks for curing me of my desire to get one of these.

The current models are apparently ok. Wet clutch, which realistically won't wear out and is certainly not vulnerable to the engine seal failure which traditionally took out BMW clutches, and from what I gather they don't require the bike to be returned to kit form to change it. Also they finally got rid of the Bochum indicator switches.

I'm aware, I read it. You made the counter-claim "EVs are not complicated." and attempted to justify it by switching the context.

And just like you, I mirrored your comments format with my own when I led with a counterpoint, and then immediately followed it up with the concession that in the context you're describing, they don't have to be.

> have a much harder time imagining how a modern ICE works as reliably as it does

Lube is magic.

I wouldn't buy a car without ESC, that's just batshit crazy, esp. if you live where there's a chance of icy roads.

Nothing I own has ESC. It's not even close to an issue. Maybe I'd feel differently if I had something with a ton of power but I don't. None of these technologies prevent you from coming into a turn or stop or other situation too hot which is far and away the biggest problem in snow and is easily doable independent of vehicle equipment.

Sure if you got good tires, good weather, drive very cautiously, have long wheelbase vehicle - it will never be used.

Drive a bit faster on gravel road and FAFO. Puddle on a highway - hope you can brake quick enough to trigger ABS and save your ass. Taking a bend with a bit more speed than you should and there's some dirt - RIP. There's some snow and you drive Smart - you'll be spinning even with the best of tires.

Sure it can be avoided. It saved my ass about 5 times. 4 of which I was simply going too fast, but once it wasn't my fault.

I'd suggest getting car with one and try to spin it out of control either on gravel or snow. Pretty sobering.

Yes mostly propaganda and being first/having a big driving base. They are notoriously closed/locked down from the diagnostic/reprogramming perspective.

What car isn't these days?

VW cars pre SFD lock

It’s funny how I extrapolate car design sessions in my head based on software design sessions. I sold my bmw after 15 years of multiple bmws because their design is so poor for maintenance. I had cooling system problems that required hours of labor to get to just to replace a plastic part that cost $5 where an aluminum one would cost $7. It seems to me that bmw was designing for best case scenarios where everything g…

> 9 things have to happen in sequence This is literally how all software works. Except it is thousands of instructions. Further, it is very often that programs don’t handle anything besides the happy path.

I like to think I design my programs to handle many situations and to be able to function with many parts that still fail.

Entirely agree, although I think it varies by make / model. Roughly look for whenever a particular car got OBDII, which makes diagnostics way easier (and was kinda the perfect level of digitization, again in my opinion), through (as you say) whenever they started digitizing the cockpit and/or (which oddly - maybe? - coincide, in my experience) manufacturers stopped considering ease of maintenance in engineering decis…

Mid 2008s saw a lot of cost cutting after the financial crisis, and then some very weird engineering decisions to deal with increased efficiency laws that made for much more complicated engines and transmissions even in smaller cars, if the smaller cars even continued to exist. Early 2000s JDM coupes will always hold a soft spot in my heart, even though they've mostly rotted away at this point. I used to say I was in…

Interesting. I kinda skipped that era of cars. Went from a mid-nineties Miata - which I still have, mostly maintain myself, and will never sell - to a 2015 CX-5, which I like, and seems well-made, but isn't exactly friendly to DIY. It's barely had any problems, though, through 150k miles, so that's not exactly a complaint.

No question, though, my next utility-car will be electric, and (though you'll have to pry it from my cold dead fingers) I expect my Miata to be the last ICE car I'll ever own.
