Last week, two companies, Kitty Hawk and Uber, announced their plans to bring flying cars to reality very soon. Sooner than you think, flying cars may appear in the skies.

On the other hand, imagine having to avoid drones and other flying cars. Also, what if your battery dies when you are in the air? And, how will you know where to land?
