Yep.
What makes that movie car so unusual is that the "wheels" are in fact spheres.
The idea has been floating around since about the mid 1970's, but no-one has as yet (so far as I know of) succeeded in making a sphere with integrated electric traction-guidance-motor, let alone 4 of them co-ordinating together powering and partly guiding a vehicle.
The Audi RSQ is thus far, unique in cinema history for that reason: depicting the concept as an actuality.
Mebd2010 my friend, you did extremely well in capturing that aspect of the vehicle.
Kind and Respectful Regards Mbed2010 my friend, Uyraell.
