It may become simpler in some regards (drive train with fewer moving parts) but I think you can take your mind off the "do it yourself" part. The SW and electronics are always proprietary with little chance you'll ever (legally) have access to them. If anything their situation will get a lot worse as "always connected" cars become more common. Most likely trying to change/mod anything there will be detected and trigger some reaction that could go all the way to flagging your car as no longer street legal. And what's left for you to repair? The simplicity you ask for will be introduced exactly where these home repairs used to happen: oil, filters, spark-plugs, a hose here, a cap there, etc. But the rest of the car stays mostly the same or gets even more complex. Most mechanical parts that aren't touched by the transition from ICE to electric motor could stay the same (suspensions, brakes), while the interior electronics will become more or less the equivalent of today's smartphones. Too complex for most people to try fixing themselves.

That's a good point about most of the home repairs we do being replaced by... not having those parts in the first place.

> The SW and electronics are always proprietary with little chance you'll ever (legally) have access to them. There's really not that much critical software in a passable electric car. I would argue that electric drive reduces the complexity of many things which require software in modern cars: ESC, TCS, (some forms of) ABS, preferred differential behaviors. In an internal combustion car, everything requires a considerable amount of knowledge specific to internal combustion engines and the complex drivetrains they make necessary. In an electric car (specifically with independent motors), TCS, light ABS, and ESC all become a matter of applying standard control theory, and tuning handful of parameters to model human expectations. Now, when it comes to something as complex as a Tesla (nonstandard door latches, window seals, etc. which make software necessary to operate the basic mechanisms of doors [which could otherwise be straightforward]), you're going to see a lot more software involved. Ultimately, the software required to make a basic independent electric drive vehicle operate is pretty small, and could be produced to a reasonable standard of quality by an intermediate programmer in a matter of months. The knowledge required to make one which manages traction and stability effectively could be learned and applied in some additional months by that same caliber of developer. The power circuitry may be more interesting, but ultimately is well within the competence of a practicing electronic engineer (and ultimately, a significant number of Joes Public who are interested enough to read a manual).

Hmm, a car that phones home to tattle on the owner? I forsee a strong future market for 'classic' vehicles. And 'disconnect service', ha!
