It'll interesting to see the transition. As dealerships would be less dependent on Service departments for profits in the future. As you get away from the standard dealership model, changes will have to be made, the question is, how do they change a multi-billion dollar a year industry, into something else. We all know service departments are very lucrative operations, and I'm sure Manufacturers will build the car to still have some maintenance reliance. Things like suspension components, steering, etc, would still need service, and EV's are at the moment, great at destroying tires. Computer errors, electronic glitches etc, for at least now would require specialized tools to access and repair, until the car computer can Diagnose and repair on it's own.
There are some positive trade offs as well, fixing cars with a scan tool, vs specialized knowledge of ICE. The service industry will adapt and overcome as it has in the past. The service departments have already survived major innovations to the ICE. Whether we are talking about materials, and tolerance specs, to software and computer based systems.
