Uber's flying taxis may be ready for a ride by 2028

Uber may help commuters avoid congested roads with its plan to develop flying taxis. 

The ride-hailing service has unveiled an artist's impression of the sleek, futuristic machine it hopes to start using for demonstration flights in 2020 and deploy for ride-sharing by 2028. The company is working with NASA on the technology, according to Reuters. 

The battery-powered aircraft looks like a cross between a small plane and a helicopter, with fixed wings and rotors. It was presented at a technology conference Wednesday in Lisbon, Portugal.

The vehicle is intended to soar over traffic congestion, sharply reducing city travel times. Uber hopes it will eventually cost commuters less than using their own car.

The scheme still faces plenty of challenges, though, including certification of the new vehicle by authorities, pilot training and conceiving urban air traffic management systems.
