For years, movies about the future have featured flying cars, and today we're closer to seeing them become reality. However, while the concept of flying cars is tremendously exciting, it could become a nightmare.
That's because, without the safety mechanisms we take for granted on the road today – traffic lights, stop signs, speed limits, etc. – the risk of crashes and collisions is very high.
Fortunately, researchers from MIT are already working on ways to solve this futuristic safety problem.
