That's neat, I'm looking forward to electric vehicles with the sort of modularity and space they are envisioning due to the extra space.

EV already have much smaller gearboxes, because they don't need to shift.
Now they need 4 of them, not just 1.
Such a gain in weight :-)

I don't need video(s) to understand the subject here : I just use an image search :

This is a mechanical device that allows coupling of any wheels of any vehicles to any electric motor.
it is designed in such a way to permit vertical movement of the wheel without the need of such movement of the motor. So basically it is a new type of suspension.
Since it needs many gears in a row for the transit of mechanical energy it will incure an inefficiency factor.
