A self-driving Uber SUV struck and killed 49-year-old Elaine Herzberg as she walked her bicycle across a street
in Tempe, Arizona, Sunday night, according to the Tempe police. The department is investigating the crash.
Rafael Vasquez, a 44-year-old test driver from Uber, was behind the wheel of the Volvo XC90 SUV at the time, the police said.
Based on preliminary information, the car was going approximately 40 mph in a 35 mph zone, according to Tempe Police Detective Lily Duran.
Police say the investigation does not at this time show significant signs of the SUV slowing before the crash. The Maricopa County Attorney's Office will determine whether charges will be filed.
"The vehicle involved is one of Uber's self-driving vehicles," the Tempe police said in a statement. "It was in autonomous mode at the time of the collision, with a vehicle operator behind the wheel."
Autonomous mode means the car is driving on its own. During tests, a person sits behind the wheel as a safeguard.
