Uh....I don't think so. Also, flying cars in 15 years? Another far fetched prediction.
Well if you consider that the taylor aerocar was built and licensed for both road and air back all the way samewhere near 1949, it makes you wonder what went wrong.
Look at the advancements in aeronautics since then, and we SHOULD be in flying cars. Unfortunately we have stringent road laws and stingent air laws requiring loads of exams and hours practice. And that unfortunately is the killer, as not many people have the money to do both.
Maybe thats a good thing ?
