PAL-V
John Bakker, A Dutch entrepreneur, has worked to develop the unique PALV(Personal Air and Land Vehicle), an unusual single-occupancy vehicle which drives like an enclosed motorcycle on the ground and like auto gyro in the air. This allows it to leap into the air on short notice, and cruise around at altitudes below the level of commercial air traffic (4,000 feet). It runs on petrol like a conventional car and can reach speeds of up to 200 km/h both on land and in the air. Read more at PAL-V
