The U.S. government has opened a formal investigation into Tesla91裸聊视频檚 Autopilot partially automated driving system after a series of collisions with parked emergency vehicles.
The investigation covers 765,000 vehicles, almost everything that Tesla has sold in the U.S. since the start of the 2014 model year. Of the crashes identified by the National Highway Traffic Safety Administration as part of the probe, 17 people were injured and one was killed.
NHTSA says it has identified 11 crashes since 2018 in which Teslas on Autopilot or Traffic Aware Cruise Control have hit vehicles at scenes where first responders have used flashing lights, flares, an illuminated arrow board or cones warning of hazards. The agency announced the action Monday in a posting on its website.
The probe is another sign that NHTSA under President Joe Biden is taking a tougher stance on on automated vehicle safety than under previous administrations. Previously the agency was reluctant to regulate the new technology for fear of hampering adoption of the potentially life-saving systems.
The investigation covers Tesla91裸聊视频檚 entire current model lineup, the Models Y, X, S and 3 from the 2014 through 2021 model years.
The National Transportation Safety Board, which also has investigated some of the Tesla crashes dating to 2016, has recommended that NHTSA and Tesla limit Autopilot91裸聊视频檚 use to areas where it can safely operate. The NTSB also recommended that NHTSA require Tesla to have a better system to make sure drivers are paying attention. NHTSA has not taken action on any of the recommendations. The NTSB has no enforcement powers and can only make recommendations to other federal agencies.
Last year the NTSB blamed Tesla, drivers and lax regulation by NHTSA for two collisions in which Teslas crashed beneath crossing tractor-trailers. The NTSB took the unusual step of accusing NHTSA of contributing to the crash for failing to make sure automakers put safeguards in place to limit use of electronic driving systems.
The agency made the determinations after investigating a 2019 crash in Delray Beach, Florida, in which the 50-year-old driver of a Tesla Model 3 was killed. The car was driving on Autopilot when neither the driver nor the Autopilot system braked or tried to avoid a tractor-trailer crossing in its path.
91裸聊视频淲e are glad to see NHTSA finally acknowledge our long standing call to investigate Tesla for putting technology on the road that will be foreseeably misused in a way that is leading to crashes, injuries, and deaths,91裸聊视频� said Jason Levine, executive director of the nonprofit Center for Auto Safety, an advocacy group. 91裸聊视频淚f anything, this probe needs to go far beyond crashes involving first responder vehicles because the danger is to all drivers, passengers, and pedestrians when Autopilot is engaged.91裸聊视频�
Autopilot has frequently been misused by Tesla drivers, who have been caught driving drunk or even riding in the back seat while a car rolled down a California highway.
A message was left early Monday seeking comment from Tesla, which has disbanded its media relations office.
NHTSA has sent investigative teams to 31 crashes involving partially automated driver assist systems since June of 2016. Such systems can keep a vehicle centered in its lane and a safe distance from vehicles in front of it. Of those crashes, 25 involved Tesla Autopilot in which 10 deaths were reported, according to data released by the agency.
Tesla and other manufacturers warn that drivers using the systems must be ready to intervene at all times. In addition to crossing semis, Teslas using Autopilot have crashed into stopped emergency vehicles and a roadway barrier.
The probe by NHTSA is long overdue, said Raj Rajkumar, an electrical and computer engineering professor at Carnegie Mellon University who studies automated vehicles.
Tesla91裸聊视频檚 failure to effectively monitor drivers to make sure they91裸聊视频檙e paying attention should be the top priority in the probe, Rajkumar said. Teslas detect pressure on the steering wheel to make sure drivers are engaged, but drivers often fool the system.
91裸聊视频淚t91裸聊视频檚 very easy to bypass the steering pressure thing,91裸聊视频� Rajkumar said. 91裸聊视频淚t91裸聊视频檚 been going on since 2014. We have been discussing this for a long time now.91裸聊视频�
The crashes into emergency vehicles cited by NHTSA began on Jan. 22, 2018 in Culver City, California, near Los Angeles when a Tesla using Autopilot struck a parked firetruck that was partially in the travel lanes with its lights flashing. Crews were handling another crash at the time.
Since then, the agency said there were crashes in Laguna Beach, California; Norwalk, Connecticut; Cloverdale, Indiana; West Bridgewater, Massachusetts; Cochise County, Arizona; Charlotte, North Carolina; Montgomery County, Texas; Lansing, Michigan; and Miami, Florida.
91裸聊视频淭he investigation will assess the technologies and methods used to monitor, assist and enforce the driver91裸聊视频檚 engagement with the dynamic driving task during Autopilot operation,91裸聊视频� NHTSA said in its investigation documents.
In addition, the probe will cover object and event detection by the system, as well as where it is allowed to operate. NHTSA says it will examine 91裸聊视频渃ontributing circumstances91裸聊视频� to the crashes, as well as similar crashes.
An investigation could lead to a recall or other enforcement action by NHTSA.
91裸聊视频淣HTSA reminds the public that no commercially available motor vehicles today are capable of driving themselves,91裸聊视频� the agency said in a statement. 91裸聊视频淓very available vehicle requires a human driver to be in control at all times, and all state laws hold human drivers responsible for operation of their vehicles.91裸聊视频�
The agency said it has 91裸聊视频渞obust enforcement tools91裸聊视频� to protect the public and investigate potential safety issues, and it will act when it finds evidence 91裸聊视频渙f noncompliance or an unreasonable risk to safety.91裸聊视频�
In June NHTSA ordered all automakers to report any crashes involving fully autonomous vehicles or partially automated driver assist systems.
Shares of Tesla Inc., based in Palo Alto, California, fell 3.5% at the opening bell Monday.
Tesla uses a camera-based system, a lot of computing power, and sometimes radar to spot obstacles, determine what they are, and then decide what the vehicles should do. But Carnegie Mellon91裸聊视频檚 Rajkumar said the company91裸聊视频檚 radar was plagued by 91裸聊视频渇alse positive91裸聊视频� signals and would stop cars after determining overpasses were obstacles.
Now Tesla has eliminated radar in favor of cameras and thousands of images that the computer neural network uses to determine if there are objects in the way. The system, he said, does a very good job on most objects that would be seen in the real world. But it has had trouble with parked emergency vehicles and perpendicular trucks in its path.
91裸聊视频淚t can only find patterns that it has been 91裸聊视频榪uote unquote91裸聊视频� trained on,91裸聊视频� Rajkumar said. 91裸聊视频淐learly the inputs that the neural network was trained on just do not contain enough images. They91裸聊视频檙e only as good as the inputs and training. Almost by definition, the training will never be good enough.91裸聊视频�
Tesla also is allowing selected owners to test what it calls a 91裸聊视频渇ull self-driving91裸聊视频� system. Rajkumar said that should be investigated as well.
