Investigators examining this week’s fatal crash involving a pedestrian struck by a self-driving Uber are scrutinizing the vehicle’s automated driving technology, and why it didn’t register a pedestrian in the middle of the road before the collision. On Friday, Velodyne, which makes LIDAR sensors used by Uber, said its technology isn’t at fault in the crash.

LIDAR, a laser-based radar that allows an autonomous vehicle to see the road, is a crucial piece of hardware for self-driving car developers. The crash occurred around 10 p.m. Sunday, but industry experts say the LIDAR system should have no problems seeing in the dark.

Many players in the industry rely on Velodyne’s LIDAR, including Uber. And a top executive at the company it’s “baffled” that Uber’s Volvo XC90 failed to recognize the victim, 49-year-old Elaine Herzberg.

, president of , maker of the special laser radar that helps an autonomous car “see” its surroundings, said the company doesn’t believe its technology failed. But she’s surprised the car didn’t detect 49-year-old Elaine Herzberg as she her bike across a road in Tempe, Arizona, around 10 p.m. on Sunday.

“We are as baffled as anyone else,” Thoma Hall wrote in an email. “Certainly, our Lidar is capable of clearly imaging Elaine and her bicycle in this situation. However, our Lidar doesn’t make the decision to put on the brakes or get out of her way.”

What she’s saying is, LIDAR’s ultimately capable to handle seeing the road—especially in the ideal conditions in Tempe, Arizona, on Sunday—so the issue must’ve been a breakdown in Uber’s autonomous vehicle software.

She said that lidar has no problems seeing in the dark. “However, it is up to the rest of the system to interpret and use the data to make decisions. We do not know how the Uber system of decision-making works,” she added.

Recognizing continues to be a challenge for autonomous technology, which will be part of the focus of the investigation. Thoma Hall suggested that those answers will be found at Uber, not Velodyne.

That jibes with comments from experts who study autonomous cars. Earlier this week, University of South Carolina law professor Bryant Walker Smith told Jalopnik that Uber’s equipment “absolutely” should’ve detected Herzberg on the road.

The issue, he said, is that the tech quite likely “classified her as something other than a stationary object.”

And that’s why Velodyne believes the “problem lies elsewhere,” Thoma Hall told Bloomberg.

“We at Velodyne are very sad, and sorry about the recent Uber car accident which took a life,” she told the news outlet. “David Hall, company CEO, inventor and founder, believes the accident was not caused by Lidar.”

Update: The headline of this post has been altered to reflect that Velodyne’s comments deflected blame away from its technology, not that it directly blamed Uber.
