Can you name one of these that exist in an EV that doesn't exist in an ICE vehicle? The issue is the same across the board. Notice a child can build a remote control car. Nothing complicated about a battery (gas tank) and a motor. It's the controllers to the windows, locks, on screen entertainment, wipers, sun roof, trunk/hood latches, antilock breaks, that become the worry of software/firmware being tied into.

The ice motor ends up being more complicated, as you regulate timing for spark plugs, fuel injectors, and how lean the fuel is as it enters at different speeds. Electric motors don't need that part.
