It might be pricey, but the Transition works exactly as claimed.
Though not really a flying car in the Blade Runner sense of the word, the Terrafugia Transition is nonetheless a vehicle which can both fly and be driven on the roads. Its flying ability was recently publicly demonstrated for the first time at the EAA AirVenture air show in Oshkosh, Wisconsin. The vehicle is street legal, and has a top speed of 65mph, but Terrafugia would prefer that you think of it as a plane that can go on the road if needed, rather than a flying car.
The price comes to a staggering $279,000, and although planes are always expensive, keep in mind that a Cessna Skycatcher is $149,000. Such is the price of versatility.
