In summary, AAA recently tested 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. very encouraging because it concerns safety.
Each vehicle could detect a dummy vehicle traveling slowly in the same direction as the test vehicle. At each test (five runs per vehicle), the test vehicle applied the brakes and adjusted the stand-in speed to avoid a collision.
Likewise, all test vehicles were able to detect a simulated cyclist traveling in the same direction and reduce their speed to avoid a collision.
When the dummy vehicle was placed in the same lane to simulate a head-on collision by a disabled or distracted driver, the test vehicles collided with it each time.
The speed of the test vehicle and the simulated oncoming vehicle were 25 mph and 25 mph, respectively — lower than what could happen in the real world. The Hyundai and Subaru made no attempt to brake and hit the target without slowing down. The Tesla braked on every test, but still managed to crash into the dummy vehicle at an average speed of 2.3 mph.
In addition, the Subaru Forester could not detect a simulated cyclist crossing the street in front of it. Both the Tesla and the Hyundai were able to brake during this test to avoid the impact.
Greg Brannon, AAA’s director of automotive engineering, said their tests show that 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 focusing 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 the AAA report as part of our continued commitment to customer safety.” Subaru told the publication they were reviewing the test to better understand AAA’s methodology, but did not have a detailed answer at this time.
