We are going to greatly miss pick'n'pull and other salvage yards when they are gone. Countless families keep their older vehicles running by salvaging parts at weekends so they can get to work on Monday and keep a roof over their head.
EV aftermarket is expensive, DRM makes parts picking v difficult, plus few people understand EVs and are scared of being electrocuted.
There are some companies that make aftermarket replacement controllers for motors and stuff, although they are generally performance oriented.
I hope in time more 3rd party repair options open up, due to sheer tenacity or competent right to repair legislation.
The next generation of vehicles are likely to drive away themselves if you haven't made payments and even drive themselves to be crushed.

Then this isn't really an EV problem, it's an industry problem.
