Tesla vehicles have been involved in nearly 300 crashes involving its driver-assisted systems.
The National Highway Traffic Safety Administration has reported that from July of last year through 15 May, vehicles using Autopilot, “Full Self-Driving," Traffic Aware Cruise Control, or other driver-assist systems were in 273 crashes.
The next automaker with the highest was Honda. Honda reported 90 crashes using driver assisted systems, but Honda says it has about six million vehicles on roads in the United States. Subaru was next with 10, and all other automakers reported five or fewer.
Tesla has about 830,000 vehicles with the systems on the road, and while chief executive Elon Musk has claimed that accidents cannot be the fault of Tesla - as data it extracted shows that Autopilot is not active in collisions - the NHTSA has said that it found 16 instances where Autopilot “aborted vehicle control less than one second prior to the first impact”. Tesla’s features are deemed assistance systems, where the driver is liable at all times.
In a June 2021 order, NHTSA told more than 100 automakers and automated vehicle tech companies to report serious crashes within one day of learning about them and to disclose less-serious crashes by the 15th day of the following month. The agency is assessing how the systems perform and whether new regulations may be needed.
“As we gather more data, NHTSA will be able to better identify any emerging risks or trends and learn more about how these technologies are performing in the real world,” said Steven Cliff, the agency's administrator.
NHTSA also said that five people were killed in the crashes involving driver-assist systems, and six were seriously hurt.
Tesla's crash number also may be high because uses telematics to monitor its vehicles and get real-time crash reports. Other automakers don't have such capability, so their reports may come slower or crashes may not be reported at all, NHTSA said. A message was left seeking comment from Tesla.
Tesla’s crashes accounted for nearly 72 per cent of the 392 reported by the dozen automakers. Although the Austin, Texas, automaker calls its systems Autopilot and “Full Self-Driving,” it says the vehicles cannot drive themselves and the drivers must be ready to intervene at all times.
Manufacturers were not required to report how many vehicles they have on the road that have the systems, nor did they have to report how far those vehicles traveled, or when the systems are in use, NHTSA said. At present, those numbers aren't quantifiable, an agency official said.
However, NHTSA may seek such information later. In the meantime, the new data has enabled it to find out about crashes much faster than before. At present, it's using the crash data to look for trends and discuss them with the companies, the agency said.
The NHTSA has used the data to seek a recall, open investigations and provide information for existing inquiries, officials said. Also, they said it's difficult to find out how many drivers actually use the technology.
“This will help our investigators quickly identify potential defect trends that can emerge,” Mr Cliff said. “These data will also help us identify crashes that we want to investigate and provide more information about how people in other vehicles interact with the vehicles."
Honda said it has packaged the systems to sell more of them, which could influence its numbers. “The population of vehicles that theoretically could be involved in a reportable event is much greater than the population of vehicles built by automakers with a less-aggressive deployment strategy,” the company said.
Also, reports to NHTSA are based on unverfied customer statements about whether automated systems were running at the time of a crash. Those crashes may not qualify for reporting to NHTSA after more data is gathered, Honda said.
The Alliance for Automotive Innovation, which represents most automakers, said the data collected by NHTSA isn't sufficient by itself to evaluate the safety of automated vehicle systems.
NHTSA's order also covered companies that are running fully autonomous vehicles, and 25 reported a total of 130 crashes. Google spinoff Waymo led with 62, followed by Transdev Alternative Services with 34 and General Motors-controlled Cruise LLC with 23.
Waymo has far more vehicles in use than other companies, and it's running a fully autonomous ride-hailing service in Arizona and California.
In 108 of the crashes involving fully autonomous vehicles, no injuries were reported, and there was only one serious injury. In most of the crashes, vehicles were struck from the rear.
