Would you take a ride in a pilotless sky taxi?

Tech companies are competing to develop the first viable passenger-carrying sky taxis, whether manned or pilotless, but how soon could these clever copters really be whizzing over our cities? And would you trust one? Dubai is racing to be the first to put drone taxis in the air. In June, its Roads and Transport Authority (RTA) signed an agreement with a German start-up Volocopter to test pilotless air taxis towards the end of this year. The firm has received 25m euros (£22m; $30m) from investors, including German motor manufacturer Daimler, to develop the 18-rotor craft capable of transporting two passengers at a time.
