Teslas account for 70% of driver-assisted crashes, knowledge exhibits

How secure are automated driving methods? Are some safer than others?

Seven years after Tesla started promoting vehicles geared up with what it calls Autopilot, auto security regulators nonetheless cannot reply these fundamental and important questions.

However they took a step towards doing so Wednesday with the Nationwide Freeway Site visitors Security Administration’s first report on crashes involving superior driver help methods.

The numbers are telling, with Tesla accounting for 70% of all crashes involving “Degree 2” driving methods, which embody adaptive cruise management and automatic lane conserving and may embody extra superior options resembling automated shifting lane That determine is bound to offer ammunition to critics who say Elon Musk’s firm has taken a reckless strategy to launching unproven expertise.

However far more element and context is required earlier than regulators can say definitively whether or not such methods can outperform human drivers or one another.

“The information could elevate extra questions than it solutions,” NHTSA chief Steven Cliff informed reporters.

In June 2021, the company required automakers to report severe crashes involving Degree 2 methods. The numbers reported Wednesday replicate crashes that occurred between then and Might 15 of this 12 months.

Of all of the crashes that occurred throughout that interval involving all vehicles, automakers reported that 392 concerned automated driver help methods.

Of those, 273 had been reported by Tesla, 90 by Honda and 10 by Subaru; others reported severe accidents within the single digits.

“This knowledge gives a restricted view of a whole bunch of crashes,” mentioned Bryant Walker Smith, a professor specializing in automated automobile legislation on the College of South Carolina Faculty of Legislation. “However in the identical interval there have been actually thousands and thousands of different accidents.”

However nobody ought to conclude that Degree 2 methods are safer than vehicles operated solely by human drivers, he mentioned. They could be, they might not. NHTSA’s knowledge is simply too broad to attract such conclusions, he mentioned.

The information doesn’t embody the variety of automated methods every firm has on the highway or the full automobile miles pushed with Degree 2 methods activated. NHTSA didn’t touch upon how thorough every firm’s notification procedures may be. The company plans month-to-month experiences.

Accidents that had been prevented by automated methods “clearly go unreported to the extent that they did not occur,” Smith mentioned. An in-depth evaluation of the reason for reported crashes — the roles performed by the system, the driving force, the system’s driver management system and different highway circumstances — would assist security regulators attain agency conclusions, he mentioned.

“What NHTSA supplied was a ‘fruit bowl’ of knowledge with many caveats, making it tough for the general public and specialists to grasp what’s being reported,” Jennifer Homendy, president of the Nationwide Transportation Security Board, mentioned in a press release. . “Unbiased knowledge evaluation is essential to figuring out safety gaps and potential treatments.”

Final 12 months’s crash knowledge reporting order marked NHTSA’s first try to fill a deep information hole concerning the real-life security implications of automated automobile expertise on public roads.

Any automobile producer’s automated system might be safer than human drivers. Or much less certain. Information wealthy sufficient to attract sturdy conclusions are scarce. Crash knowledge assortment methods in the USA are a long time previous, inconsistent, nonetheless paper-based in lots of police departments, and never totally geared up to find out the position automated methods play in stopping or inflicting crashes.

“I’d have hoped that NHTSA would do the work to make the numbers they publish in summaries actually comparable,” Alain Kornhauser, head of Princeton College’s driverless automotive program, mentioned in an e-mail.

Along with gathering crash knowledge, NHTSA is investigating why Tesla vehicles have crashed into emergency autos parked on the facet of the highway, typically with emergency lights flashing.

The investigation was prompted by 11 crashes that resulted in 17 accidents and one demise, together with three crashes in Southern California. The variety of such accidents has elevated to 16. The expertise in about 830,000 vehicles – all Tesla autos offered in the USA from 2014 to 2022 – is beneath investigation.

As a part of that investigation, regulators will take a look at the efficiency of Tesla’s automated emergency braking methods. As The Occasions reported final 12 months, Tesla drivers report emergency braking issues at a a lot larger fee than drivers of different manufacturers.

The investigation into the emergency automobile turned extra severe earlier this month, when NHTSA raised its standing to “EA” for engineering evaluation. That class means researchers will look extra carefully on the technical design and efficiency of the autopilot. As soon as an investigation reaches EA, a takedown is extra seemingly.

In the meantime, the California Division of Motor Automobiles continues to research whether or not Tesla is falsely advertising its full self-driving characteristic, a $12,000 choice. Specialists within the discipline overwhelmingly word that the system doesn’t come near with the ability to drive itself safely.

The DMV evaluation, nonetheless, is greater than a 12 months previous, and the DMV won’t say when it might be accomplished.

State lawmakers are more and more involved concerning the DMV’s apparently lax strategy to Tesla. In December, California Senate Transportation Committee Chairwoman Lena Gonzalez requested the DMV to offer accident and security data to the committee. The DMV mentioned they’d look into it and are nonetheless trying.

The DMV seems to be permitting Tesla to check self-driving vehicles on public roads with out requiring the corporate to report accidents or system failures, as rivals like Waymo, Cruise, Argo and Zoox are required to do. DMV chief Steve Gordon has declined all media requests to debate the difficulty since Might 2021.
