Self-driving aerial taxis have been the plan since Airbus first announced the concept back in August 2016. While the CityAirbus' look finally settled on a quad-rotor design familiar to any drone fan, the mission has remained constant: A vertical take-off and landing (VTOL) electric-powered aircraft that will nimbly schlep four passengers through urban areas. The four-fan design should cut down on noise and the craft's size, while splitting rides between a quartet of passengers could make it as cheap as a regular cab ride.

Of course, Airbus isn't the only one to think it's a good idea. Uber devoted a three-day summit to its flying taxi plans, which aim to have a test vehicle airborne by 2020, while Dubai just saw the maiden trial of a two-seated, 18-rotor taxi prototype built by the German company Volocopter. Looks like you'll climb into a cab flown by a human (or computer) long before your own flying car (despite Airbus teasing a concept vehicle), but considering how much trouble we have driving on two axes, maybe that's for the best.
