DETROIT (AP) Three crashes involving Teslas that killed three people have increased scrutiny of the companys Autopilot driving system just months before CEO Elon Musk has planned to put fully self-driving cars on the streets.
On Sunday, a Tesla Model S sedan left a freeway in Gardena, California, at a high speed, ran a red light and struck a Honda Civic, killing two people inside, police said.
On the same day, a Tesla Model 3 hit a parked firetruck on an Indiana freeway, killing a passenger in the Tesla.
And on Dec. 7, yet another Model 3 struck a police cruiser on a Connecticut highway, though no one was hurt.
The special crash investigation unit of the National Highway Traffic Safety Administration is looking into the California crash. The agency hasnt decided whether its special-crash unit will review the crash that occurred Sunday near Terre Haute, Indiana. In both cases, authorities have yet to determine whether Teslas Autopilot system was being used.
NHTSA also is investigating the Connecticut crash, in which the driver told police that the car was operating on Autopilot, a Tesla system designed to keep a car in its lane and a safe distance from other vehicles. Autopilot also can change lanes on its own.
Tesla has said repeatedly that its Autopilot system is designed only to assist drivers, who must still pay attention and be ready to intervene at all times. The company contends that Teslas with Autopilot are safer than vehicles without it, but cautions that the system does not prevent all crashes.
Even so, experts and safety advocates say a string of Tesla crashes raises serious questions about whether drivers have become too reliant on Teslas technology and whether the company does enough to ensure that drivers keep paying attention. Some critics have said its past time for NHTSA to stop investigating and to take action, such as forcing Tesla to make sure drivers pay attention when the system is being used.
NHTSA has started investigations into 13 Tesla crashes dating to at least 2016 in which the agency believes Autopilot was operating. The agency has yet to issue any regulations, though it is studying how it should evaluate similar advanced driver assist systems.
At some point, the question becomes: How much evidence is needed to determine that the way this technology is being used is unsafe? said Jason Levine, executive director of the nonprofit Center for Auto Safety in Washington. In this instance, hopefully these tragedies will not be in vain and will lead to something more than an investigation by NHTSA.
Levine and others have called on the agency to require Tesla to limit the use of Autopilot to mainly four-lane divided highways without cross traffic. They also want Tesla to install a better system to monitor drivers to make sure theyre paying attention all the time. Teslas system requires drivers to place their hands on the steering wheel. But federal investigators have found that this system lets drivers zone out for too long.
Tesla plans to use the same cameras and radar sensors, though with a more powerful computer, in its fully self-driving vehicles. Critics question whether those cars will be able to drive themselves safely without putting other motorists in danger.
Doubts about Teslas Autopilot system have long persisted. In September, the National Transportation Safety Board, which investigates transportation accidents, issued a report saying that a design flaw in Autopilot and driver inattention combined to cause a Tesla Model S to slam into a firetruck parked along a Los Angeles-area freeway in January 2018. The board determined that the driver was overly reliant on the system and that Autopilots design let him disengage from driving for too long.
In addition to the deaths on Sunday night, three U.S. fatal crashes since 2016 two in Florida and one in Silicon Valley involved vehicles using Autopilot.
David Friedman, vice president of advocacy for Consumer Reports and a former acting NHTSA administrator, said the agency should have declared Autopilot defective and sought a recall after a 2016 crash in Florida that killed a driver. Neither Teslas system nor the driver had braked before the car went underneath a semi-trailer that had turned in front of the car.
