The Transition drives like a car, uses normal high-octane gasoline, has front-wheel-drive and even comes with airbags. Its fuel economy is about 30 miles per gallon. But unlike your Prius, it can unfold its wings and fly. You'll only need a one-third of a mile strip for a runway, meaning you could conceivably use your own street. It is powered by a rear propeller and flies about 115 miles per hour.
