The first public use of driverless taxis is underway in Singapore.

nuTonomy, the software developer behind the technology, has launched its autonomous taxi service in Singapore's one-north business district, and is offering free rides to select residents. The taxis, modified Mitsubishi i-MiEVs and Renault Zoes, can be hailed through nuTonomy's smartphone app. Though the vehicles will drive themsevles, a nuTonomy engineer will be in the car at all times, and can take over in emergency situations. 

nuTonomy's goal is to use this launch as a trial run. They aim to have a commercial fleet of autonmous taxis on the streets of Singapore by 2018.
