Once batteries are improved you can easily see why electric motor powered vehicles will reign supreme regardless of the climate BS. Water pumps, tensioners, belts, chains, exhaust manifolds, fluids, et al. All major BS to deal with in modern cars.
All this BS will probably be replaced by another BS with electronics and software... Software bugs would concern me more than a leaky water pump.
Yep, I'd rather swap out a water pump, something I can physically touch and see, than chase down some software bug.
EVs do have a lot fewer moving components though, so, long-term, the auto repair industry will need to shift and/or right-size dramatically...Tires, brakes, suspension, still wear and will be ripe for maintenance and repair, but as AS points out, lots of core part categories that'll be killed off as EV proliferation increases.
That said, their will be new parts to replace....modules, computers, electric motors, harnesses, etc. Sorta like an extreme version of the transition from Carbs to EFI....Not selling many Qjet rebuild kits these days, but plenty injectors, rails, regulators, etc.
