Uber may have switched off safety system before fatal crash, Bloomberg reports

Ride-hailing app Uber may have turned off a standard safety system in a Volvo SUV before the self-driving vehicle fatally struck a woman in Arizona last week, according to a report.

A spokesperson for Michigan basedauto-parts makerAptivPlc, which supplies Volvo with the vehicle'sradar and camera,told Bloombergthat Uberdisabled the SUV'sstandard collision-avoidance technology.

"We don't want people to be confused or think it was a failure of the technology that we supply for Volvo, because that's not the case," saidZach Peterson ofAptiv, according to the news agency.

A dashcam video of the crashreleased by Arizona police showed that the self-driving Volvothat Uber was testing did not slow as Elaine Herzbergcrossed the street while pushing her bicycle at night.

The car was in self-driving mode with a human backup driver behind the wheel when it hit the 49-year-old woman.

She later died in hospital and wasthe first death involving a fully autonomous test vehicle in the U.S.. After the death, Uberhalted testing of all its self-drivingcars in all cities.

Uber did not respond when asked byCBCNewsif the companyhad disabled the car's standard collision-avoidance technology before the crash.

Regarding the next steps it plans to take, Ubersaid the company'sautonomous cars remain grounded.

"We're heartbroken by what happened last week," the spokesperson said in a statement. "As we develop self-driving technology, safety is our primary concern every step of the way."

CBC News contacted theNational Highway Traffic Safety Administration (NHTSA), which regulates vehicle performance standards in the U.S., to ask if Uber waslegally required to leave the car's standard collision safety technology enabled during testing.

The agency did not answer about specific legal requirements, saying the case wasan open and active investigation.

"Consistent withNHTSA's vigilant oversight and authority over the safety of all motor vehicles and equipment, including automated technologies, the agency has dispatched its Special Crash Investigation team to Tempe, Arizona," it said in astatement.

"NHTSAis also in contact withUber, Volvo, Federal, State and local authorities regarding the incident. The agency will review the information and proceed as warranted."

Banned in Arizona

The report comes as Arizona Gov. Doug Duceysuspended the tech giant's autonomous vehicletesting privileges in the state on Monday.

In a letter to Uber'schief executiveDaraKhosrowshahi, Duceysaid the video footage of the crash heightened concerns over whether Uberhad the ability to safely test the technology in Arizona.

He said in a series of tweetsthat he was "personally very disturbed" by the video and it raised questions that need to be answered with the help of federal investigators.

"I want to see the facts," he said. "Arizona has allowed this technology to test and flourish. We will continue to encourage innovation. But public safety comes first. It's always been our focus and it will remain our focus."

Ubertold CBCNewsin a statement that it would"continue to help investigators in any way we can, and we'll keep a dialogue open with the Governor's office to address any concerns they have."

'Experience' in detection

Meanwhile, some experts whohave viewed the video of the crash say the Volvo's sensors should have seen the woman crossing the road and stopped before the crash.

In a blog post, Intel Mobileye'sCEO AmnonShashuawrote that it used the video of the crash to test its own software and was able to detect the woman one second beforeimpact despite the poor quality of the video.

Intel Mobileyeis a supplier to Aptiv, but it's not clear if the Mobileyetechnology was in the Ubercar that fatally struck the woman.

"To demonstrate the power and sophistication of today's ADAS technology, we ran our software on a video feed coming from a TV monitor running the police video of the incident," he said."Despite the suboptimal conditions, where much of the high dynamic range data that would be present in the actual scene was likely lost, clear detection was achieved approximately one second before impact."

"The software being used for this experiment is the same as included in today's ADAS-equipped vehicles, which have been proven over billions of miles in the hands of consumers," he added.
