The NuTonomy vehicles, which are available through the Lyft app, include a human backup driver in case the vehicle runs into trouble, according to the Verge. The program marks an important step for Lyft as it competes with Uber, which has unveiled autonomous taxis in Phoenix and Pittsburgh. Those taxis include a human backup driver, but the company has unveiled an ambitious plan to put completely driverless Volvo Taxis on the road in 2019 - likely in the United States. Lyft, meanwhile, has partnered with at least five automakers, including Ford, GM, Waymo, Jaguar and Drive.AI, according to Recode.
