It's a car... It's an airplane... It's Terrafugia Transition. According to the company's site, "The Transition combines the unique convenience of being able to fold its wings with the ability to drive on any road service in a modern personal airplane platform." Sounds like a Pontiac Aztec with airfoils.
Hey, you gotta give Terrafugia props -- a pusher prop, in fact -- for trying. One of its advertising taglines is: "Driven to Fly." The other is: "It's time to make the Transition." That conversion will set you back $279,000. Not to worry. As the FAQ notes, "the Transition provides a flexibility that cannot be matched with a separate car and airplane."
I think I speak for backseat drivers everywhere when I say, thanks, but I can walk to the curb from here.
