I got the idea that you could theoretically have the best suspension on any vehicle in the world if you could have the vehicle body hover above the wheels. This would also enable the use of omni-directional "ball" wheels that would not be restricted to an axle.
My question is, assuming we were able to have an on-board cooling system that kept the bottom of the vehicle at approximately the -300 degree superconductivity threshold, would it be feasible to create this mechanism, or any variation thereof remotely resembling the aforementioned design, via the use of quantum locking, and, if not, is there perhaps another technology that could achieve the same goals?
