You are behind the times. This is a pretty well-studied and implemented thing. It is expensive, though, which is why you don’t see if more often. If a motor stops working, you can still drive the car with the other three motors. That’s SUPER simple with modern computing and software.
Now, the part where the motors are Ferrari-made… let’s see how that turns out.
I lived for 3 years with a 100 mile range EV as my only car. Very rarely did I need more range than that. When I did I just rented a car for $40/day. When I upgraded to a 220 mile range car it felt like infinite range. I was able to charge at home, though, so it was much easier to deal with.
