Nearly a week after an autonomous Uber SUV claimed the first life in testing of self-driving vehicles, the CEO of another tech company says he is confident its cars would have performed differently under the circumstances.

John Krafcik, chief executive officer of Waymo, formerly Google’s autonomous vehicle project, said Waymo’s cars are intensively programmed to avoid such calamities.
“I can say with some confidence that in situations like that one with pedestrians — in this case a pedestrian with a bicycle — we have a lot of confidence that our technology would be robust and would be able to handle situations like that,” Krafcik said Saturday during a panel at the National Automobile Dealers Association convention in Las Vegas.
Krafcik had been asked directly if a Waymo car would have reacted differently than the self-driving Uber.
“I want to be really respectful of Elaine [Herzberg], the woman who lost her life and her family,” he said. “I also want to recognize the fact that there are many different investigations going on now regarding what happened in Tempe on Sunday.”
His assessment, he said, was “based on our knowledge of what we’ve seen so far with that accident and our own knowledge of the robustness that we’ve designed into our systems.”
Krafcik was referring to 49-year-old Elaine Herzberg, who was killed last Sunday night when a self-driving Uber struck her as she walked a bicycle across a Tempe, Ariz. street. Video footage graphically illustrated how the autonomous Volvo XC90 and its backup driver failed to protect Herzberg, who was outside a marked crosswalk, as she walked across the road at around 10:30 p.m.
Waymo is testing its self-driving fleet in parts of Phoenix, where autonomous taxis are shuttling some members of the public. The company has a fleet of Chrylser Pacifica minivans with custom-designed hardware that undergoes rigorous testing, including in open and closed environments and through rigorous computer simulations, according to a Waymo spokeswoman.

Asked the basis on which Krafcik made his claim, Waymo pointed to its hardware and testing regimen, which includes closed-course testing at night in which pedestrians sometimes unexpectedly enter the roadway, according to the company. The cars operate on public roads and pull data from those situations to create simulations of cities where Waymo operates, such as Phoenix and Austin. Under that setup, Waymo says, the company can repeat a single testing scenario thousands of times.
Waymo says its equipment has run through thousands of scenarios focused exclusively on avoiding collisions involving pedestrians. The vehicles are equipped with custom LIDAR, radar equipment and other sensors, according to Waymo.
Last fall, Waymo became the first company to issue a detailed safety report to federal officials on its self-driving vehicle program, under a voluntary self-assessment program. The 43-page safety report detailed the company’s efforts to account for everyday road scenarios that lead to automobile crashes:

“We’ve staged people jumping out of canvas bags or porta-potties on the side of the road, skateboarders lying on their boards, and thrown stacks of paper in front of our sensors,” Waymo said in its report.
Uber has yet to submit a safety letter to the National Highway Traffic Safety Administration, but said it is in the process of doing so. The company has said its self-driving cars are equipped with a suite of sophisticated equipment:
A top-mounted LIDAR unit, which relies on lasers to scan the environment and provide an unobstructed view of the car’s surroundings; seven cameras, including a front-facing lens observing for factors such as pedestrians, and side and rear cameras for a more comprehensive view — in addition to other components.
Uber did not immediately respond to an inquiry about the Waymo CEO’s claim.
On Saturday’s panel in Las Vegas, Krafcik said he respected the multiple investigations into the crash and would not speculate on what went wrong. The National Transportation Safety Board is among the agencies investigating the wreck.
“For those of us at Waymo it was a very sad day,” Krafcik said. “Because that was an accident that was in a car that had technology representing the self-driving space. And for those of us at Waymo it is that mission of safety and avoiding accidents just like that one that really brings us all together as a company. It struck us in a really major way.”
