Just imagine a car or motorcycle enhanced with spherical wheels capable of moving in any direction free. The car body would be suspended on 2 or 4 spherical wheels rolling in any direction driver chooses. The engine would deliver its power to such wheels not by means of axles, but through special rollers.

It's gonna be the next generation of cars, omni-moving!

Post Scriptum: hmhm... I also gotta invent the way a steering wheel of such a vehicle would look.
