Was reading the Times Online article that the flying car from Massachusetts based Terrafugia is getting close to reality. The wings of the car fold up so that it's about the same size as a big SUV - all in about 15 seconds! An amazing feat of engineering and inventiveness.
My only concern would be safety. If this vehicle was treated as a plane, then I'm ok with it. I think airplane safety regulations are pretty strict so if any person who owned one of these needed to have a full pilot's license, that would be a must. As the old saying goes, nobody ever died when their car ran out of gas.
