Uber self-driving taxi crash: Shocking video shows moments before autonomous car killed pedestrian

'This is strongly suggestive of multiple failures of Uber and its system, its automated system, and its safety driver'

Video has emerged of the self-driving vehicle crash that is thought to have been the first time an autonomous vehicle has killed a pedestrian.

The footage shows a pedestrian walking across the road from a darkened area onto a street. It captures the moment the car and the human driver who sits in it for safety sees her – before the car collides with her.

It shows that the lights on the self-driving SUV didn't shine on 49-year-old Elaine Herzberg on Sunday night until a second or two before impact. But it has raised questions over why the car – which shouldn't need its headlights to see hazards – didn't spot the pedestrian and stop.

The crash Sunday night in Tempe was the first death involving a full autonomous test vehicle. The Volvo was in self-driving mode with a human backup driver at the wheel when it struck Herzberg, police said.

The video shows the human backup driver in the SUV looking down until seconds before the crash. The driver looks up and appears startled during the last moment of the clip.

Tempe Police Chief Sylvia Moir has told the San Francisco Chronicle that the SUV likely wouldn't be found at fault. But two experts who viewed the video told The Associated Press that the SUV's laser and radar sensors should have spotted Herzberg and her bicycle in time to brake.

"The victim did not come out of nowhere. She's moving on a dark road, but it's an open road, so Lidar (laser) and radar should have detected and classified her" as a human, said Bryant Walker Smith, a University of South Carolina law professor who studies autonomous vehicles.

Smith said the video may not show the complete picture, but "this is strongly suggestive of multiple failures of Uber and its system, its automated system, and its safety driver."

Sam Abuelsmaid, an analyst for Navigant Research who also follows autonomous vehicles, said laser and radar systems can see in the dark much better than humans or cameras and that Herzberg was well within the range.

"It absolutely should have been able to pick her up," he said. "From what I see in the video it sure looks like the car is at fault, not the pedestrian."

Smith said that from what he observed on the video, the Uber driver appears to be relying too much on the self-driving system by not looking up at the road.

"The safety driver is clearly relying on the fact that the car is driving itself. It's the old adage that if everyone is responsible no one is responsible," Smith said. "This is everything gone wrong that these systems, if responsibly implemented, are supposed to prevent."

The experts were unsure if the test vehicle was equipped with a video monitor that the backup driver may have been viewing.

Uber immediately suspended all road-testing of such autos in the Phoenix area, Pittsburgh, San Francisco and Toronto. The National Transportation Safety Board, which makes recommendations for preventing crashes, is investigating the crash.

An Uber spokeswoman, reached Wednesday night by email, did not answer specific questions about the video or the expert observations.

"The video is disturbing and heartbreaking to watch, and our thoughts continue to be with Elaine's loved ones. Our cars remain grounded, and we're assisting local, state and federal authorities in any way we can," the company said in a statement.
