I think that there will be plenty of moving parts on these cars to break.
I wonder what its like repairing a ‘regenerative braking system’...and I’m sure the batteries (only warranteed to 80k miles) put a dent in the pocketbook. I ran some numbers, with subsidy, and the break even was 400k miles, assuming only one battery replacement. I don’t think there are enough dumb greenies to buy all these cars, so the gubmint will buy them for their fleet, and declare a green success.
regen is just using the vehicle energy to turn the motor instead of vice versa.
it really only involves some electrical contactors switching
I doubt that will be much of a wear item
and it does take a lot of the energy out of the wheel brakes
I know on the hybrid transit buses the wheel brake life is 3 to 5 times longer.
