This company is pretty serious as it turns out. Their "Transition" roadable car is on schedule for delivery in 2015 or so. This next video (TF-X) is a sort of personal Osprey and is not as far- fetched as it looks, because tilt rotor technology is currently available (see the other thread on Autonomous Rotors). The aircraft does all the landing and takeoff maneuvering itself. You have to overlook the Dubai disco music.
