Really, go watch "The Jetsons". From what I can read, you have no vision of your own, just the idea that someone else might be able to do something eventually. So, Elon Musk says, "building a flying car wouldn't be that difficult", and you say, "yeah, what he said". So, in my book, that is jumping on the bandwagon. As I said in my last post, the people that know the least about aerodynamics and aviation protocol, are making the most noise about flying cars being possible. FWIW, guest is way more on target than you.
