The top U.S. auto safety regulator said the agency is seeking additional details of a recent accident involving a Google self-driving car in California.
The National Highway Traffic Safety Administration is collecting information to get a “more detailed exploration of what exactly happened,” NHTSA chief Mark Rosekind told Reuters on the sidelines of an event on highway safety.
A Google self-driving car struck a municipal bus in Mountain View, Calif., in a minor crash on Feb. 14, and the technology company said it bears “some responsibility” for the incident in what may be the first crash that was the fault of the self-driving vehicle.
Rosekind said he spoke to Google officials and the company has been “very forthcoming” in answering requests for details on the crash. “We have to see what’s going on,” Rosekind said.
A Google spokesman confirmed NHTSA has asked for more information and the company plans to discuss the crash with regulators.
U.S. safety officials said in January they are working on new guidance on self-driving vehicles that they hope to release by July. Rosekind said understanding the Google car crash is important in that process.
“One of the lessons learned would be: there’s an incident, how do you make sure that the issue ends up getting corrected and there is quality assurance to make sure it effectively changes what happened,” Rosekind said.
Google said last week it made changes to its software after the crash to avoid future incidents. A U.S. Senate panel will hold a hearing on the future of autonomous vehicles that will include the director of Google’s self-driving car program.
Last month, NHTSA said the artificial intelligence system piloting a self-driving Google car could be considered the driver under federal law, a major step toward winning approval for autonomous vehicles on the roads.
The California Department of Motor Vehicles said it is also reviewing the Google crash.
California rules say the state could “suspend or revoke the manufacturer’s testing permit for any act or omission which the department finds makes the conduct of autonomous vehicle testing on public roads an unreasonable risk to the public,” the agency said.
