With the advent of driverless cars and electric cars and drones, we need to look towards the future. People have successfully made drones that can carry one person plus baggage and fly at over 60 mph under controlled flight. As these vehicles get more powerful and larger, we will have the ability to have hover cars. No more worrying about potholes! Maybe?
A study needs to be done to determine how this type of vehicle can safely fit into the transportation system.
