Umm. That video is 2 years old. So is there any new news?

And as with all these, including the Terrafugia Transition, the Klein AirCar will be both a bad car, and a bad plane. There are just too many conflicting requirements to make any single vehicle perform well in both areas. In almost all practical cases, everyone will be better off with a plane and a cars (or 10 cars, one at each airfield to which one flies regularly), instead of one of these, and it will be cheaper, too. And available now. And faster (92 knots cruise? Really? A Cherokee 140 is faster), have higher payloads, etc., etc.
