The Transition® street-legal flying car is a plane with wings that can fold up, allowing it to drive on normal roads. It gets about 35mpg on land and goes through about 5 gallons per hour in the air. It’s not quite the flying Delorean from the Back to the Future series, but it’s a step in the right direction. It’ll cost about $279,000 and is manufactured by Terrafugia in Woburn, Massachusetts.
