Uber car kills woman

A pedestrian in Arizona has died after being hit by a self-driving car operated by Uber in what appears to be the first known such death on a public road.

A self-driving Uber SUV struck and killed a pedestrian in suburban Phoenix in the first death involving a fully autonomous test vehicle — an accident that could have far-reaching consequences for the new technology.

The crash Sunday night in Tempe was the event many in the auto and technology industries were dreading but knew was inevitable.

Uber immediately suspended all road-testing of such autos in the Phoenix area, Pittsburgh, San Francisco and Toronto. The testing has been going on for months as automakers and tech companies like the ride-hailing service compete to be the first with cars that operate on their own.

The Volvo was in self-driving mode with a human backup driver at the wheel when it hit 49year-old Elaine Herzberg as she was walking a bicycle outside the lines of a crosswalk, police said. She died at a hospital. Tempe police Sgt. Ronald Elcock said Monday the agency hasn't drawn any conclusions about who is at fault.

Uber CEO Dara Khosrowshahi expressed condolences on his Twitter account and said the company is working with local law enforcement on the investigation.

The National Transportation Safety Board, which makes recommendations for preventing crashes, and the National Highway Traffic Safety Administration, which can enact regulations, sent investigators.

The public's image of the vehicles will be defined by stories like the crash in Tempe, said Bryant Walker Smith, a University of South Carolina law professor who studies self-driving vehicles.

Although the Uber vehicle and its human backup could be at fault, it may turn out that there was nothing either could have done to stop the crash, he said.
