BURNSVILLE, MN (Aug. 6, 2020) – Although designed to assist drivers in order to reduce or eliminate traffic crashes, AAA is warning drivers to be cautious of trusting certain vehicle technology.

What are termed “Active Driving Assistance” systems are designed to assist drivers and make the roads safer; however, AAA researchers warn the technology is far from 100-percent reliable.

While there are various forms of Advanced Driver Assistance Technologies in vehicles today, Active Driving Assistance (ADA) is unique in that it combines functionalities like steering, acceleration and braking. AAA’s research focused on five vehicles equipped with Active Driving Assistance. View the full report.

Real-World Testing

AAA automotive researchers found that over the course of 4,000 miles of real-world driving, vehicles equipped with active driver assist systems experienced some type of issue every 8 miles, on average. Researchers noted instances of:

  • Trouble keeping vehicles in the lane and coming too close to other vehicles or guardrails.
  • Systems often disengaging with little notice – almost instantly giving control back to the driver.

On public roadways, nearly three-quarters (73%) of all system errors involved instances of lane departure or erratic lane position. These systems currently rely on in-vehicle cameras to determine lane position. Just like our eyes, the cameras struggle to “see” when lane markings are not clear or when the sun is providing too much glare. Also, lane changes can happen suddenly, causing the vehicle to struggle in a more complex driving environment.

“Active Driving Assistance Systems may lull drivers into a false sense of security, encouraging them to direct their attention away from driving,” said Gene LaDoucer, director of public affairs for AAA-The Auto Club Group in North Dakota. “When using these systems, it is critical drivers remain focused on the road and not rely solely on the technology to keep them safe.”

Disabled Vehicles

In closed-course testing, AAA researchers found that the systems performed mostly as expected, but were challenged when approaching a simulated disabled vehicle parked partially in the roadway. When encountering this test scenario, in aggregate, a collision occurred 66 percent of the time and the average impact speed was 25 mph, slowing just 5 mph from the original speed.

Recommendations

AAA has met with industry leaders to provide insight from the testing experience and shared its recommendations for improvement. Recommendations include increasing the scope of testing for active driver assistance systems and limit their rollout until functionality is improved to provide a more consistent and safer driver experience.

“With the number of issues experienced in testing, it’s unclear how these systems enhance the driving experience in their current form,” said LaDoucer.  “A bad experience with current technology can set back public acceptance of more fully automated vehicles in the future.”

AAA’s 2020 automated vehicle survey found that only one in ten drivers (12%) would trust riding in a self-driving car. To increase consumer confidence, AAA says it’s important that car manufacturers perfect functionality as much as possible before deployment in a larger fleet of vehicles 

Methodology
AAA conducted closed-course testing and naturalistic driving in partnership with the Automobile Club of Southern California’s Automotive Research Center and AAA Northern California, Nevada and Utah’s GoMentum Proving Grounds. Using a defined set of criteria, AAA selected the following vehicles for testing:  2019 BMW X7 with “Active Driving Assistant Professional”, 2019 Cadillac CT6 with “Super Cruise™”, 2019 Ford Edge with “Ford Co-Pilot360™”, 2020 Kia Telluride with “Highway Driving Assist” and 2020 Subaru Outback with “EyeSight®” and were sourced from the manufacturer or directly from dealer inventory. The 2019 Cadillac CT6 and the 2019 Ford Edge were evaluated only within naturalistic environments.
