What would life be like if we all could fly?

Would there be any use for airplanes or cars at all anymore? Would everyone be able to fly or just certain people? What kind of laws would there be in place for those who could fly? How far would we be able to fly before getting exhausted. It would be interesting to see how technology would change if we could fly. I wonder if we would be able to fly out of earth’s atmosphere or if we would have to stay in it. It would be amazing if we could fly into space under our own will power. I would like exploring other planets and galaxies and I’m sure there are many others who would like to also.
