Well about the flying car, there is a guy I believe in southern California who is currently developing one. He has already tested it semi-successfully I believe. The FDA or w/e the air part of the government is called, does not want just random people able to fly around. All air cars would do is basically add more lanes, except in the air. There would be no free flight, it would all be strictly controlled and kept in check. I think they want to be able to control each vehicle as well, to keep them on the set path.
