EV motors have less parts and therefore less failure modes than gas engines. Tesla’s really don’t have a transmission either so that’s another major subtraction of failure modes.
I talked to a guy who had a 2014 59000 mile Chevy 1500 with a 6.2 gas engine. The truck was like new. He was driving it to a dealership to trade it off on a new one. The engine blew up on the way. Valve spring broke and there was piston to valve contact and total destruction. New engine was 15k.
So? Millions upon millions of cars have done this country just fine.
