Driver Assistance Systems Defeated By Rain

The American Automobile Association (AAA) recently conducted a new study to see how advanced safety features perform in bad weather. To test their performance, the AAA used a closed course and simulated moderate to heavy rainfall. It also simulated other real-world conditions, like dirt and bugs.

The results are shocking considering that a new generation of drivers has more confidence in these systems, not knowing anything else butLevel 2 autonomous vehicles. These new safety systems can actually have the opposite effect, creatingdangerous distracted drivers.

Vehicles equipped with automatic emergency braking were driven down a road at 35 mph in the aforementioned conditions, colliding with an inflatable Fiesta 33% of the time. Lane-keep assist has an even more challenging time, with vehicles departing their lanes 69% of the time.

The AAA states that these safety features are usually tested in ideal operating conditions and that it believes real-world situations need to be incorporated as well. Considering the result of this study, we're inclined to agree. We also can't help but be reminded of the AAA's studies conducted in2019and2014.

"Vehicle safety systems rely on sensors and cameras to see road markings, other cars, pedestrians, and roadway obstacles. So naturally, they are more vulnerable to environmental factors like rain," said Greg Brannon, AAA's director of automotive engineering and industry relations. "The reality is people aren't always driving around in perfect, sunny weather, so we must expand testing and take into consideration things people actually contend with in their day-to-day driving."

A look at the aggregate results gives even more insight. The automatic emergency braking was tested at 17 mph, in which case the cars only crashed in 17% of test runs. At 35 mph, the figure essentially doubled to 33%.

"AAA recognizes these systems have the ability to lessen the chance of a crash and improve the overall safety of driving," continued Brannon. "Fine-tuning their performance and providing drivers with a more consistent experience will go a long way in unlocking their true potential."
