Driver assist systems installed in Tesla, Hyundai Motor and Subaru vehicles all failed to avoid frontal collisions in tests conducted by the American Automobile Association (AAA).
The AAA, a US consumer services and travel organization, said current driver assistance and automated braking systems fall short of true autonomous driving and require drivers to maintain control of vehicles.
The organization backed up these claims with the performance of assisted driving systems installed in Tesla, Hyundai Motor and Subaru cars in recent tests, in which not all vehicles managed to avoid frontal collisions. Tesla’s Autopilot system, however, slowed the vehicle to walking speed before hitting an oncoming foam car model.
A growing number of new vehicles are equipped with Automated Driver Assistance Systems (ADAS), which serve to partially automate functions such as steering, lane keeping and braking. Tesla’s Autopilot is one of the best-known such systems, but most major automakers offer similar technology.
Regulators, car insurers and automakers have long warned that ADAS systems cannot safely replace the full attention of a human driver, and these tests appear to back up their claims.
In their latest study on the limits of assisted driving technology, the AAA researchers defined four tasks for the three models tested: passing a dummy car traveling in the same direction as the tested vehicle; pass a dummy cyclist going in the same direction; race a dummy car on a head-on collision course at 25 miles per hour (40 km/h) and avoid a dummy cyclist crossing the path of the test car
All three test vehicles detected and avoided hitting the dummy vehicles and cyclists traveling in the same direction ahead of the test vehicles, AAA said. However, the Hyundai Santa Fe and Subaru Forester do not appear to sense or slow to avoid colliding with the foam dummy vehicle in a simulated frontal collision, AAA said.
Tesla’s Model 3, on the other hand, automatically braked when it detected the oncoming dummy car, slowing to 3.2 miles per hour (5 km/h) or less before colliding with the car. dummy.
Tesla did not respond with comment on the study. Hyundai said in a statement that it is “reviewing the findings of the AAA report as part of our ongoing commitment to customer safety,” while Subaru said it was reviewing the AAA test to understand the methodology and didn’t have a detailed answer yet. .
Despite these findings, many governments have gone ahead with approvals for testing ADAS systems, or even driverless cars and buses. The UK itself has started testing the first fully self-driving bus in Scotland and has approved legislation to prevent drivers of self-driving vehicles from being blamed for crashes.
