If cars can float on air, suspend themselves some 30 or 40 meters above the ground, then run from there, I wonder how the traffic would look like. You may say it would be like the Star Wars movies, but I think not.
There would be no need for tires, certainly. But then perhaps every driver would be required to wear jumpsuits with helmets. Instead of traffic enforcers we would have air traffic controllers. Around airports, I'm sure by this time planes can also hover and land vertically. Thus, there will be no more runways.
Whew! An anti-gravity device can make a lot of things obsolete and the face of the world would change, literally speaking. We would talk of "wheels" and "expressways" and our round-eyed grandchildren would ask, "What's that, Grandpa?"
