MIT already has your flying car in miniature form

Some drones fly, others drive. Those that can do both, however, can reach places other machines can't, making them ideal for search and rescue -- or package delivery. That's why a team from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a fleet of autonomous drones that have rotors and wheels, giving them the capability avoid obstacles on the ground and to go underneath overhead obstructions. Just imagine a machine that can fly to a disaster zone and then drive in the gaps of collapsed buildings to search for survivors. The team based these new drones on a previous "flying monkey" robot one of them developed.
