Airtrax omnidirectional wheels

Remember the adage of not reinventing the wheel? Well Airtrax decided to go against common sense by coming up with omnidirectional wheels that strangely enough, actually work! These will target industrial vehicles by rolling forward, back, sideways and diagonally. Hmmm, it would be interesting to see these make an appearance on passenger cars as it would surely go great lengths in helping those who suffer from difficulty in parallel parking, especially in tighter spots.
