It appears the hybrid technology is taking electric motor design clues from Diesel Electromotive technology used in RR locomotives.

I'm not sure why you can't have this type of system in cars? Why not have individual motors at each hub with a central power source?
This would make things like stability control easy, have all wheel drive, and you would eliminate the weight of a mechanical transmission. Regenerative breaking should also be easy.

and it would be fun to be able to make your car spin about its central axis, in winter

NASA beat you and mitsu to the punch by a few years.

Sounds like an electric fork truck.

1. Cost (4x the motors, motor drivers, and control complexity in failure recovery)
2. Weight (more motors vs drive shafts/axles)
3. Reliability (4x as many parts that can break)
The day that motors weight less than axles and cost less than axles will be the day with direct drive wheels.
