Uber car did not slow before crash

- By Carolyn Said

Police in Tempe, Ariz., on Wednesday released damning dashcam videos of the fatal accident Sunday night in which an Uber car operating in autonomous mode struck and killed a pedestrian, showing the car did not slow down or alter its course to avoid her.

The first five seconds of the 21-second clip show a car’s-eye view of the road ahead with an obstacle visible in the lane that turns out to be a woman wearing blue jeans and a black top slowly walking a red bicycle. It ends just before the moment of impact. The woman, Elaine Herzberg, 49, died of her injuries at a hospital.

The rest of the clip shows the backup driver inside the car, looking down. It ends abruptly with the driver’s mouth falling open, presumably at the moment of impact.

“The video clearly shows a complete failure of the system to recognize an obviously seen person who is visible for quite some distance in the frame,” said Michael Ramsey, research director with Gartner and an expert on self-driving cars.

“Uber has some serious explaining to do about why this person wasn’t seen and why the system didn’t engage.”

The self-driving car was equipped with sensors, including video cameras, radar and lidar, a laser form of radar. Although the technology is still under developmen­t, robot cars are intended to be superior to human drivers because they have a 360degree view of their surroundin­gs and don’t get distracted.

While video cameras capture better views with more light, the car’s other sensors should not have been affected by the nighttime hour.

“There is no question the laser should have seen her,” said Brad Templeton, a Silicon Valley entreprene­ur who was an early consultant on Google’s self-driving project. “I know the technology is better than that, so I do feel that it must be Uber’s failure.”

Uber has suspended tests of autonomous vehicles in all four cities where it operates them — Tempe, San Francisco, Pittsburgh and Toronto. The accident, the first pedestrian fatality involving a robot car, has cast a shadow on the nascent industry.

Police have said there is no sign that the selfdrivin­g Volvo SUV, which was traveling at 38 mph, slowed before the impact. Although the video does not show it, the police explanatio­n of the woman’s route across the road means that she had already crossed two lanes before she was in front of the car.

Although the car was driving itself, it had a backup driver behind the wheel, whose role was to take control if necessary. The driver has been identified as Rafaela Vasquez, 44. The Arizona Republic reported that she served almost four years in a state prison for attempted armed robbery and unsworn falsificat­ion, and was released in 2005.

“It’s clear the safety driver is distracted, looking down right up until the impact,” Ramsey said. “It brings up a whole slew of questions about Uber’s system and how it could possibly have not detected that.” Templeton agreed. “The safety driver did not do her job properly,” he said. “The driver’s job is to remain vigilant on the road situation.”

Ramsey and Templeton both said that the automatic braking and forward-collision warning that are stock features on high-end car such as the Volvo XC90 that Uber uses in its tests should have detected the pedestrian and at least slowed the car.

“Probably, that Volvo had it, but it was turned off,” Templeton said.

“The video is disturbing and heartbreak­ing to watch, and our thoughts continue to be with Elaine’s loved ones,” Uber said. “Our cars remain grounded, and we’re assisting local, state and federal authoritie­s in any way we can.”

Sylvia Moir, Tempe police chief, told The Chronicle on Monday that from her viewing of the video, it appeared that neither the driver nor the self-driving car were at fault. She did not respond to an inquiry Wednesday about whether she had reconsider­ed that statement.
