Slow down there, the concept isnt coming to sports cars, or any cars any time soon. The "wheels" are un-inflated, have silly unsprung weight. They would suck for a sports car, and wouldnt work at all on a bike (you need at least 4 of them). They are good for tight, slow manuvering. Expect to see them on wheelchairs, small drone like robots, things along these lines.
Its not all around better than a normal wheel, just better at a certain application at expanse of the rest. Still, freaking cool. Wish I would've thought of that.
