Automakers and tech developers testing and deploying self-driving and advanced driver assistance features will no longer have to report as much detailed, public crash information to the federal government, according to a new framework released today by the US Department of Transportation. The moves are a boon for makers of self-driving cars and the wider vehicle technology industry, which has complained that federal crash reporting requirements are overly burdensome and redundant. But the new rules will limit the information available to those who watchdog and study autonomous vehicles and driver assistance features--tech developments that are deeply entwined with public safety but which companies often shield from public view because they involve proprietary systems that companies spend billions to develop. The government's new orders limit "one of the only sources of publicly available data that we have on incidents involving Level 2 systems," says Sam Abuelsamid, who writes about the self-driving vehicle industry and is the vice president of marketing at Telemetry, a Michigan research firm, referring to driver assistance features such as Tesla's Full Self-Driving (Supervised), General Motors' Super Cruise, and Ford's Blue Cruise. These incidents, he notes, are only becoming "more common."

The National Highway Traffic Safety Administration (NHTSA) has implemented a new policy that will require car companies to report incidents involving semi- and fully autonomous driving systems within one day of learning of an accident. In an order spotted by The Washington Post, NHTSA mandates automakers fill out an electronic incident form and submit it to the agency when one of their systems was active either during a crash or immediately before it. They must report an accident anytime there's a death, an injury that requires hospital treatment, a vehicle that's towed away, an airbag deployment or when a pedestrian and or cyclist is involved. The order covers Level 2 advanced driver-assistance systems to Level 5 fully autonomous vehicles, meaning it includes the gamut of everything from Tesla cars with Autopilot to Waymo taxis. "This action will enable NHTSA to collect information necessary for the agency to play its role in keeping Americans safe on the roadways, even as the technology deployed on the nation's roads continues to evolve," the regulator said.
