My increasing fear is that EVs just have mechanics' eyes on them a lot less frequently, so preventative maintenance on brakes and the other mechanical parts doesn't get done. Which means, on a heavier vehicle as well, more risk of catastrophic failures during use and vehicles on the used market being junk.

A heavier vehicle also will wear tires faster, and my observation of other cars on the street is that people as a whole are very bad about not replacing tires on time.
