I wonder what the service ceiling is on that thing? I can't imagine something like that even remotely going mainstream in a metro area where there is a large airport nearby or even a smaller controlled airport. I think that is the biggest problem with the "Flying Car" concept. We all know how bad the drivers of cars are out there. Can you imagine people buzzing around Charlotte, Raleigh, or even the Triad while ATC is relying on these folks to stay below a certain altitude?
