If you're gonna go through all this trouble, why not put motors directly into the wheels? Then you can bypass the drivetrain all together and directly power the wheels.
If you put the motor in the wheel you increase the unsuspended mass. Bad for handling and ride quality
4 motors is more expensive than 1 motor and a bunch of gears
Do really need need 4?
If you cant get by on 2, you might have less power, but you can get better efficiency. With better efficiency you can have a smaller battery for the same range and reduce some of your increased cost that way.
And also, if one of the wheel motors breaks down will the inevitably obtuse software of the car allow me to drive on three wheels, or will it sit idle until a certified technician arrives and inputs a service code?
We both know the answer to that question. And boy howdy am I stoked for cars to get fully enshittified where you have to have a yearly subscription for the software that allows your tires to move, otherwise you functionally just bought a 45,000 dollar paperweight.
