I agree that the car repair industry will be hurting due to electric vehicles, but not for the same reasons. As Tesla has shown, locking out non-corporate repairs is easy, even body work is something you can choke out from 3rd party shops by refusing to provide parts (hence the incredible repair costs for Tesla vehicles).

A profit driven electric car company can decide that any minor damage to the car will mean they push out a firmware update to brick the car. You don't own the software that makes the vehicle function, hence your at the mercy of the manufacturer letting you use their software.
