In Brief: AAA recently conducted tests on three vehicles equipped with an Active Driver Assistance System (Level 2): a 2021 Hyundai Santa Fe, a 2021 Subaru Forester, and a 2020 Tesla Model 3, and the results are unclear. are not very encouraging because it concerns security.
Each vehicle was able to detect a dummy vehicle moving slowly in the same direction as the test vehicle. In each test (five runs per vehicle), the test vehicle applied the brakes and adapted the stand-in speed to avoid an impact.
Similarly, all test vehicles were able to detect a simulated cyclist traveling in the same direction and slow their speed to avoid an impact.
When the dummy vehicle was placed in the same lane to simulate a head-on collision caused by an impaired or distracted driver, the test vehicles crashed into it every time.
The speed of the test vehicle and the simulated oncoming vehicle were 25mph and 15mph, respectively – lower than what might happen in the real world. The Hyundai and Subaru made no attempt to apply the brakes and hit the target without reducing speed. The Tesla applied the brakes on each test, but still managed to crash into the dummy vehicle at an average speed of 2.3 mph.
Additionally, the Subaru Forester failed to detect a simulated cyclist crossing the street in front of it. Both the Tesla and the Hyundai were able to brake to avoid the impact during this test.
Greg Brannon, AAA’s director of automotive engineering, said their testing demonstrates uneven performance is the norm rather than the exception.
AAA’s advice to automakers is simple: listen to consumers and improve the systems currently available before trying to focus on the future. “You can’t sell the future to consumers if they don’t trust the present,” Brannon added.
Tesla did not respond to a request for comment from Reuters. A Hyundai representative said it was “reviewing the findings of AAA’s report as part of our ongoing commitment to customer safety.” Subaru told the publication that they were reviewing the test to better understand AAA’s methodology, but did not have a detailed response at this time.
