WAYNE, N.J., August 13, 2020 — AAA automotive researchers have found that over the course of 4,000 miles of real-world driving, vehicles equipped with active driving assistance systems experienced some type of issue every 8 miles, on average. As a result, AAA recommends manufacturers increase the scope of testing for active driving assistance systems and limit their rollout until functionality is improved to provide a more consistent and safer driver experience.
Researchers noted instances of trouble with the systems keeping the vehicles tested in their lane and coming too close to other vehicles or guardrails. AAA also found that active driving assistance systems, those that combine vehicle acceleration with braking and steering, often disengage with little notice – almost instantly handing control back to the driver. That’s a dangerous scenario if a driver has become disengaged from the driving task or has become too dependent on the system.
“AAA has repeatedly found that active driving assistance systems do not perform consistently, especially in real-word scenarios,” said Robert Sinclair Jr., Manager of Media Relations for AAA Northeast. “Manufacturers need to work toward more dependable technology, including improving lane keeping assistance and providing more adequate alerts.”
AAA tested the functionality of active driving assistance systems in real-world conditions and in a closed-course setting to determine how well they responded to common driving scenarios. On public roadways, nearly three-quarters (73%) of errors involved instances of lane departure or erratic lane position.
“Active driving assistance systems are designed to assist the driver and help make the roads safer, but the fact is, these systems are in the early stages of their development,” added Mr. Sinclair. “With the number of issues we experienced in testing, it is unclear how these systems enhance the driving experience in their current form. In the long run, a bad experience with current technology may 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 in future automated vehicles, it is important that car manufacturers perfect functionality as much as possible – like active driving assistance systems available now – before deployment in a larger fleet of vehicles. AAA has met with industry leaders to provide insight from the testing experience and recommendations for improvement. The insights are also shared with AAA members and the public to inform their driving experiences and vehicle purchase decisions.
