A self-driving vehicle operated by Uber struck and killed a person in Tempe, Arizona, late Sunday evening.
Police are investigating the deadly crash. While there are many unknowns at this early juncture, Uber officials say that the vehicle was operating in autonomous mode at the time and that a human safety driver was behind the wheel.
Conflicting reports said the victim was either on foot or riding a bicycle at the time of the crash. Video footage from KNXV-TV shows a mangled bicycle on the sidewalk near the Volvo XC90 Uber that was involved.
A woman whose identity has not yet been released was transported to a local hospital, where she died of her injuries, according to the Tempe Police Department. She is believed to be the first person killed by being hit by an autonomous vehicle in the United States. An Uber spokesperson said Monday the company has temporarily stopped all testing of self-driving vehicles in the Phoenix area as well as in San Francisco, Pittsburgh, and Toronto. Uber chief executive officer Dara Khosrowshahi sent his condolences to the victim?s family via Twitter on Monday afternoon.
