Tesla Autopilot may crash more than rivals
U.S. agency will issue data on collisions involving cars with autonomous or partly automated systems.
The government will soon release data on collisions involving vehicles with autonomous or partially automated driving systems that probably will single out Tesla for a disproportionately high number of such crashes.
In coming days, the National Highway Traffic Safety Administration plans to issue figures it has been gathering for nearly a year. The agency said in a separate report last week that it had documented more than 200 crashes involving Teslas that were using Autopilot, Full Self-Driving, TrafficAware Cruise Control or some other of the company’s partially automated systems.
Tesla’s figure and its crash rate per 1,000 vehicles were substantially higher than the corresponding numbers for other automakers that provided such data to the Associated Press ahead of NHTSA’s release. The number of Tesla collisions was revealed as part of an NHTSA investigation of Teslas on Autopilot that had crashed into emergency and other vehicles stopped along roadways.
Tesla does have many more vehicles with partly automated systems operating on U.S. roads than most other automakers — roughly 830,000, dating to the 2014 model year. And it collects real-time data online from vehicles, so it has a much faster reporting system. Other automakers, by contrast, must wait for reports to arrive from the field and sometimes don’t learn about crashes for months.
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, whether they endanger public safety and whether new regulations may be needed.
General Motors said it reported three crashes while its Super Cruise or other partially automated systems were in use. The company said it has sold more than 34,000 vehicles with Super Cruise since its debut in 2017.
Nissan, with more than 560,000 vehicles on the road using its ProPilot Assist, didn’t have to report any crashes, the company said.
Stellantis, formerly Fiat Chrysler, said it reported two crashes involving its systems. Ford reported none involving its Blue Cruise driver-assist system, which went on sale in the spring,
though Ford wouldn’t say if there were crashes with lesscapable systems.
GM said the three crashes weren’t the fault of Super Cruise. It also reported two crashes that happened before the June 2021 order, a spokesman said.
Several automakers and tech companies, including Toyota and Honda, declined to release their numbers before the NHTSA data are revealed.
A message was left seeking comment from Tesla, which has disbanded its media relations department. NHTSA wouldn’t comment on the data Tuesday.
Raj Rajkumar, an electrical and computer engineering professor at Carnegie Mellon University who studies automated vehicles, said he wouldn’t be surprised if Tesla was found to have had a high number of crashes involving its driver-assist systems. Tesla, based in Austin, Texas, stopped using radar in its system and instead relies solely on cameras and
computers — a system that Rajkumar calls “inherently unsafe.”
The system’s computer, he said, can recognize only what’s in its memory. Flashing lights on an emergency vehicle, Rajkumar said, might confuse the system, as would anything that the computer hasn’t seen before.
“Emergency vehicles may look very different from all the data that the Tesla software had been trained on,” he said.
In addition to the publicly released crash data, NHTSA has sent investigative teams to far more incidents involving Teslas using electronic systems than other automakers. As part of a larger inquiry into crashes involving advanced driver assistance systems, the agency has sent teams to 34 crashes since 2016 in which the systems were thought to have been in use. Of the 34 crashes, 28 involved Teslas, according to an NHTSA document.
NHTSA said in documents that it has received 191 reports of crashes involving Teslas on Autopilot and nonemergency vehicles, and 16 more involving parked emergency vehicles or those with warning lights, for a total of 207. Of the 191, the agency removed 85 because of actions of other vehicles or insufficient data to make a firm assessment of the crashes. That left 106 that were included in the Autopilot investigation.
It was unclear whether 207 matched the total number of Tesla crashes reported to NHTSA under the order. An NHTSA spokeswoman wouldn’t comment.
The agency ordered automakers and tech companies to report crashes involving driver-assist systems as well as fully autonomous driving systems.
In defending its partially automated systems, Tesla has said that Autopilot and Full Self-Driving cannot drive themselves, and that drivers should be ready to intervene at all times. The systems can keep cars in their lanes and away from other vehicles and objects. But in documents released last week, NHTSA raised questions about whether human drivers can intervene fast enough to prevent crashes.
Tesla’s Full Self-Driving is designed to complete a route on its own with human supervision, with the eventual aim of driving itself and running a fleet of autonomous robotaxis. In 2019, Musk had pledged to have the robotaxis running in 2020.
Tesla’s Autopilot driverassist system detects hands on the steering wheel to make sure drivers are paying attention. But that’s inadequate, Rajkumar said. By contrast, systems such as GM’s monitor a driver’s eyes with a camera, he said, to make sure they’re looking forward.
We have another prominent business set to leave the state, and our government officials remain quiet. Is it any wonder that Californians are migrating to other states? The high cost of doing business in California has also prompted the departures of Nestle USA, Oracle and others.

Many of us Angelenos have fond memories of the Farmer John murals. They paint a pleasant, bucolic picture of animals grazing happily.
Having worked inside for a short while, I have a different feeling. I have seen the frightened animals come down the chute to be killed, divided into pieces and packaged, all in a very bloody and sloppy manner.
I have backed up into a shelf with pig heads staring at me. I have seen the inspector stamp the meat as approved without even inspecting them.
After my short period there there, I was a vegetarian for two years.
