One of great ironies of the 21st century is going to be that humanity had to build autonomous flying drones before it could build autonomous cars (to develop the algorithms), and autonomous cars before it could build flying cars (because average people could never be reasonably expected to pilot a flying car.) But mark my words in 2100 we will, at last, have flying autonomous cars (or something that can be described that way.)
