Most auto makers are not fully vested in making Electric Cars. Making an EV is reactionary to what they see as a niche market. Instead of building an EV from the ground up, they take their cheapest ICE car and replace components to make it an EV.
Go to any car dealership and ask 20 questions about their EV. An average salesman won't know a thing about it. The rest of their cars they memorize things like ignition timing.
