This is an improvement on a hovercraft which would allow for use on normal roads and if approved for use on highways. It uses inflated ball unattached in sockets as a "connection" to the road. It would be precisely steerable and could literally stop on a dime. Replacing a "tire" would be as simple as lifting the vehicle and rolling the old one out and rolling a new one under the socket. It would use all current technology and talk about a smooth ride!
