Here are a couple of links about Burt Rutan's latest, and maybe last effort. It is sad to hear he retired in April of this year. I'll bet he still has his hand in future designs though. The amazing thing about this "flying car", it is a hybrid.

Below are a couple of renderings done back in 1993. There are alot of similarities to the concept in the drawings and Rutan's design, even down to where the wings are stored while operating the vehicle on the ground.
It is easy to draw a picture. It is a difficult accomplishment to bring a vehicle from concept stage to reality. Burt Rutan has done this many times in his remarkable career.
