Well in this video we can see that a magnet can float above a metal once it gets frozen by liquid nitrogen and becomes a superconductor....If we could create special highways made of special metals, and then put plumbing underneath the metal road which pumps liquid nitrogen; we could have a nice road for flying vehicles. Now attach some neodymium magnets (also called rare-earth magnets) to the bottom of speciallized cars and we could have a nice little floating vehicle....add a propulsion system of some sort and you could have flying vehicles...maybe I'm just dreaming.....
