Tempe police have released footage from the onboard cameras on the self-driving Uber which was involved in a fatal self-driving car crash in Arizona recently. The video casts a different light on the incident, and has raised new questions about why the autonomous car failed to stop in time.

“While we recognize two media outlets have attributed exclusive interviews with the [police] chief, we respectfully disagree with how their claim of interviews have been characterised,” said Sgt. Ronald Elcock, a spokesman for Tempe police, in a statement.

In the video, the self-driving XC90 is shown driving on what looks like a dimly-lit road. Around the 3-second mark, we see the shoes of the victim, 49-year-old Elaine Herzberg, and a second after that is when the collision took place. According to reports, the vehicle was moving at 61 km/h (38 mph) in a 56 km/h (35 mph) zone.

Switching over the interior camera, we see backup driver 44-year-old Rafael Vasquez glancing down often for about 10 seconds leading up to the crash. Sylvia Moir, police chief in Tempe, Arizona, previously said, “it would have been difficult to avoid this collision in any kind of mode (autonomous or human-driven) based on how she came from the shadows right into the roadway.”

“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,” said an Uber spokeswoman in a statement. Uber has already stopped testing its autonomous vehicles throughout North America.

Tempe police will continue working with the National Transportation Safety Board and the National Highway Traffic Safety Administration on the matter. A case will then be submitted to the Maricopa County Attorney’s Office once the investigation is finished to decide if charges will be filed.
