The U.S.-based ride-hailing app launched the UberONE option on Tuesday in partnership with Dubai Taxi Corporation, which added 50 Tesla Model X and Model S to its fleet last month. The vehicles, which Uber riders can select for a slightly higher fare, are equipped with self-driving components.

Uber's rushing to replace its million-plus drivers with robots, and the company's early forays towards that effort start in Pennsylvania later in August. The ride-sharing service plans to roll out self-driving cars in Pittsburgh that will accept real world passengers right from the get-go, according to Bloomberg. The cars, while fully autonomous, won't be unleashed onto Pittsburgh streets without human supervision. The cars will have a specially-trained engineer ready to take the wheel should something go wrong. There will also be a co-pilot taking notes on how each ride goes.
