Self-driving and driver-assisted technology linked to hundreds of crashes
Over the course of 10 months, nearly 400 car crashes in the United States involved advanced driverassistance technologies, the federal government's top auto-safety regulator disclosed Wednesday, in its first-ever release of largescale data about these burgeoning systems.
In 392 incidents cataloged by the National Highway Traffic Safety Administration from July 1 of last year through May 15, six people died and five were seriously injured. Teslas operating with Autopilot, the more ambitious Full Self Driving mode or any of their associated component features were in 273 crashes. Five of those Tesla crashes were fatal.
The disclosures are part of a sweeping effort by the federal agency to determine the safety of advanced driving systems as they become increasingly commonplace. Beyond the futuristic allure of self-driving cars, scores of car manufacturers have rolled out automated components in recent years, including features that allow you to take your hands off the steering wheel under certain conditions and that help you parallel park.
In Wednesday's release, NHTSA disclosed that Honda vehicles were involved in 90 incidents and Subarus in 10. Ford Motor, General Motors, BMW, Volkswagen, Toyota, Hyundai and Porsche each reported five or fewer.
“These technologies hold great promise to improve safety, but we need to understand how these vehicles are performing in real-world situations,” said Steven Cliff, the agency's administrator. “This will help our investigators quickly identify potential defect trends that emerge.”
Speaking with reporters ahead of Wednesday's release, Cliff also cautioned against drawing conclusions from the data collected so far, noting that it does not take into account factors like the number of cars from each manufacturer that are on the road and equipped with these types of technologies.
“The data may raise more questions than they answer,” he said.
About 830,000 Tesla cars in the United States are equipped with Autopilot or the company's other driver-assistance technologies — offering one explanation why Tesla vehicles accounted for nearly 70% of the reported crashes.
Ford, GM, BMW and others have similar advanced systems that allow handsfree driving under certain conditions on highways, but far fewer of those models have been sold. These companies, however, have sold millions of cars over the last two decades that are equipped with individual components of driverassist systems. The components include so-called lane keeping, which helps drivers stay in their lanes, and adaptive cruise control, which maintains a car's speed and brakes automatically when traffic ahead slows.
Cliff said NHTSA would continue to collect data on crashes involving these types of features and technologies, noting that the agency would use it as a guide in making any rules or requirements for how they should be designed and used.
The data was collected under an order NHTSA issued a year ago that required automakers to report crashes involving cars equipped with advanced driver-assist systems, also known as ADAS or Level-2 automated driving systems.
The order was prompted partly by crashes and fatalities over the last six years that involved Teslas operating in Autopilot. Last week, NHTSA widened an investigation into whether Autopilot has technological and design flaws that pose safety risks. The agency has been looking into 35 crashes that occurred while Autopilot was activated, including nine that resulted in the deaths of 14 people since 2014. It had also opened a preliminary investigation into 16 incidents in which Teslas under Autopilot control crashed into emergency vehicles that had stopped and had their lights flashing.
Under the order issued last year, NHTSA also collected data on crashes or incidents involving fully automated vehicles that are still in development for the most part but are being tested on public roads. The manufacturers of these vehicles include GM, Ford and other traditional automakers as well as tech companies such as Waymo, which is owned by Google's parent company.
These types of vehicles were involved in 130 incidents, NHTSA found. One resulted in a serious injury, 15 in minor or moderate injuries, and 108 didn't result in injuries. Many of the crashes involving automated vehicles led to fender benders or bumper taps because they are operated mainly at low speeds and in city driving.
Waymo, which is running a fleet of driverless taxis in Arizona, was part of 62 incidents. GM's Cruise division, which has just started offering driverless taxi rides in San Francisco, was involved in 23. One minor crash involving an automated test vehicle made by Pony.ai, a startup, resulted in a recall of three of the company's test vehicles to correct software.
NHTSA's order was an unusually bold step for the regulator, which has come under fire in recent years for not being more assertive with automakers.
“The agency is gathering information in order to determine whether, in the field, these systems constitute an unreasonable risk to safety,” said J. Christian Gerdes, a professor of mechanical engineering and a director of Stanford University's Center for Automotive Research.
An advanced driver-assistance system can steer, brake and accelerate vehicles on its own, though drivers must stay alert and ready to take control of the vehicle at any time.
