Emergency Vehicle Lights Can Screw Up a Car's Automated Driving System

Tesla, which disbanded its nationalist relations squad successful 2021, did not respond to WIRED’s petition for comment. The camera systems the researchers utilized successful their tests were manufactured by HP, Pelsee, Azdome, Imagebon, and Rexing; nary of those companies responded to WIRED’s requests for comment.

Although the NHTSA acknowledges issues successful “some precocious operator assistance systems,” the researchers are clear: They’re not definite what this observed exigency airy effect has to bash with Tesla’s Autopilot troubles. “I bash not assertion that I cognize wherefore Teslas clang into exigency vehicles,” says Nassi. “I bash not cognize adjacent if this is inactive a vulnerability.”

The researchers’ experiments were besides acrophobic solely with image-based entity detection. Many automakers usage different sensors, including radar and lidar, to assistance observe obstacles successful the road. A smaller harvest of tech developers—Tesla among them—argue that image-based systems augmented with blase artificial quality grooming tin alteration not lone operator assistance systems, but besides wholly autonomous vehicles. Last month, Tesla CEO Elon Musk said the automaker's vision-based strategy would alteration self-driving cars adjacent year.

Indeed, however a strategy mightiness respond to flashing lights depends connected however idiosyncratic automakers plan their automated driving systems. Some whitethorn take to “tune” their exertion to respond to things it’s not wholly definite are really obstacles. In the extreme, that prime could pb to “false positives,” wherever a car mightiness hard brake, for example, successful effect to a toddler-shaped cardboard box. Others whitethorn tune their tech to respond lone erstwhile it’s precise assured that what it’s seeing is an obstacle. On the different broadside of the extreme, that prime could pb to the car failing to brake to debar a collision with different conveyance due to the fact that it misses that it is different conveyance entirely.

The BGU and Fujitsu researchers did travel with a bundle hole to the exigency flasher issue. Called “Caracetamol”—a portmanteau of “car” and the painkiller “Paracetamol”—it’s designed to debar the “seizure” contented by being specifically trained to place vehicles with exigency flashing lights. The researchers accidental it improves entity detectors’ accuracy.

Earlence Fernandes, an adjunct prof of machine subject and engineering astatine University of California, San Diego, who was not progressive successful the research, said it appeared “sound.” “Just similar a quality tin get temporarily blinded by exigency flashers, a camera operating wrong an precocious operator assistance strategy tin get blinded temporarily,” helium says.

For researcher Bryan Reimer, who studies conveyance automation and information astatine the MIT AgeLab, the insubstantial points to larger questions astir the limitations of AI-based driving systems. Automakers request “repeatable, robust validation” to uncover unsighted spots similar susceptibility to exigency lights, helium says. He worries immoderate automakers are “moving exertion faster than they tin trial it.”
