This is going to be a problem for most dealerships, as repair and service is a large chunk of their profit.
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.
For now. It's an iron law of the market economy that once this sector becomes competitive, costs will get optimized to the point that - like currently with ICE cars - the reliability will be lowest possible that they can get away with. There's no law of physics saying EVs are built reliably; there just isn't enough economic incentive to start building low-reliability parts. That will change as EVs gain popularity.
How do you service electric cars compared to ICE cars?
Will the move to electric cars fundamentally hurt the car repair industry and will you have to go back to school to learn about servicing electric engines?
Thanks!
