Played a little with 'interactive playback' simulation environment mode. Some simple ICE Kinematics and some ICE mesh and nurb deformation - and here we have quite useful auto-rotated wheel rig. I used to do it with ScOps before, but it's much easy and comfortable to built such things with ICE.

Note. If you hide nulls in viewport, it becomes a little bit buggy (but doesn't stop working at all:) ) . Strange but true.
