US revises passenger safety rules for autonomous vehicles

The U.S. government is coming out with new regulations aimed at changing automotive passenger safety standards that could be barriers to autonomous vehicles.

The National Highway Traffic Safety Administration says it's seeking comment on proposed updated standards to account for vehicles that don't have manual controls such as steering wheels or brake pedals. Autonomous vehicles also may not have drivers sitting in the traditional driver's seat.

The proposal would revise requirements and test procedures, the agency said in a statement Tuesday. It also would clarify that passenger protection standard standards don't apply to vehicles made specifically to carry goods and not people.

"We do not want regulations enacted long before the development of automated technologies to present an unintended and unnecessary barrier against innovation and improved ," NHTSA Acting Administrator James Owens said in the statement.

The proposed regulation would apply front passenger seat protection standards to the traditional driver's seat of an autonomous , rather than safety requirements that are specific to the driver's seat, the agency said. "The rationale discussed in this notice is that an occupant should not need protection from a steering control system if none exists in the vehicle," the regulation said.

The regulations would account for vehicles that operate autonomously but also can be controlled by a human in the driver's seat, NHTSA said.

NHTSA says in the regulation that much of the safety potential of automated driving systems is "unsubstantiated and the impacts unknown," but it still believes the best path forward is to remove barriers.

Jason Levine, executive director of the nonprofit Center for Auto Safety, an , said NHTSA shouldn't remove regulatory safeguards for a technology that is not proven "and in fact may be unsafe." He said in a statement that the government should focus on existing "not corporate giveaways desired by lobbyists and questioned by experts."

The public has about 60 days to comment on the proposal. Based on the comments, NHTSA would then put the rule into effect, the agency said.

The regulation is aimed at and does not address multiple recommendations from the National Transportation Safety Board made last month about partially automated vehicles with driver assist systems.

After several involving Tesla electric vehicles operating on the company's Autopilot driver-assist system, the NTSB recommended that NHTSA expand testing to make sure partially automated systems can avoid running into common obstacles such as a freeway barrier. The board also asked that NHTSA evaluate Autopilot to determine where it can safely operate, and to develop and enforce standards for monitoring drivers so they pay attention while using the systems.

NHTSA said at the time it will review the NTSB's report and that all commercially available vehicles require human drivers to stay in control at all times.
