OK, ‘roadable airplane’. But still…
Check it out: here is the real deal, Jetson’s-esque flying car…
Only the Aerocar actually works. 
Just last week I saw the only currently airworthy Taylor Car at the Kissimmee Airport in Florida.
Doesn’t look like a very good car or airplane, from what I can tell. But it has nostalgia value up the wazoo!
If I wanted an airplane, I’d buy an airplane. What I want is a VTOL skycar, but Moller’s skycar has been “in development” for pretty much my entire life, and I suspect I’ll die before that thing gets more than ten or twenty feet off the ground untethered.
My Grandfather test flew this for Aerocar back when. There was one at the San Diego Air & Space Museum in Balboa Park. Real interesting up close.
