Are Modern Driving Assistance Features Unreliable? AAA Researchers Say Yes
The American Automobile Association (AAA) is recommending automakers limit the use of advanced driving aids after concluding they’re not really up to the challenge of providing reliable safety.
Over the past two years, AAA has focused on testing crash prevention systems to see if they’re all manufacturers claim — deciding that while many are useful in some instances, they’re far too inconsistent to be considered reliable safety nets. Like us, the group worries that making these features commonplace has created a false sense of security among drivers. While one might assume advanced driving aids have to be halfway decent to be put into vehicles, AAA’s pedestrian detection test from 2019 showed they’re anything but consistent.
On Thursday, America’s favorite motor club returned to report on its latest findings on five systems currently offered by the industry. For the test, AAA selected a 2019 BMW X7 with Active Driving Assistant Professional, 2019 Cadillac CT6 with Super Cruise, 2019 Ford Edge with Co-Pilot360, 2020 Kia Telluride with Highway Driving Assist, and a 2020 Subaru Outback with EyeSight. The group was sent to numerous testing sites in California, Utah, and Nevada, and given a 4,000-mile shakedown on public roads — where the outfit found the systems averaged a misstep or disengagement roughly every 8 miles.
Problems were not isolated to turns, however. Vehicles sometimes drifted out of their lane on a straight trajectory as well, only to over-correct and find themselves in the wrong lane.
Obstacle detection was another serious issue. Testing in a closed environment, AAA found that test cars typically hit stationary obstacles ( video here) representing a disabled vehicle upon approach, rather than avoiding them. When encountering this test scenario, in aggregate, collisions occurred 66 percent of the time with an average impact speed of 25 mph.
“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,” said Greg Brannon, AAA’s director of automotive engineering and industry relations. “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.”
It also might turn you into a grease spot on the pavement if you’re not ready to handle their occasional hiccups. However, automakers have grown more vocal about how these assistance packages aren’t meant to replace an attentive driver (even though many literally steer, brake, and accelerate the vehicle for you). This has prompted loads of debate among consumer advocacy groups, which claim the language being used to sell these systems is misleading and that the systems ultimately dull a driver’s senses by lulling them into feeling overly confident in a car’s limited capabilities.
Even the way the cars were tested showcased some of the issues confronted by consumers. A few systems couldn’t be tested in a closed environment. For example, Cadillac’s Super Cruise requires a divided highway to work at all. But they all have their own personalities, with different levels of engagement and thresholds for disengagement. Ultimately, AAA said it didn’t see much (if any) improvement from the last batch of vehicles tested. The group also noted that legal experts and regulatory groups have started to caution that it may be decades before fully autonomous cars are ready for widespread deployment, and that the systems that foreshadow their arrival could be doing more harm than good.
“AAA has repeatedly found that active driving assistance systems do not perform consistently, especially in real-word scenarios,” Brannon said. “Manufacturers need to work toward more dependable technology, including improving lane keeping assistance and providing more adequate alerts.”
Researchers have released the study in full if you’d like to see the metrics used and how the vehicles stacked up against each other. AAA wants the takeaway to be that these systems are still lacking across the board. It’s recommending the auto industry cool its jets until serious improvements can be made, and to stop trying to put these advanced driving aids into every vehicle they manufacture until they’re substantially improved.
A staunch consumer advocate tracking industry trends and regulation. Before joining TTAC, Matt spent a decade working for marketing and research firms based in NYC. Clients included several of the world’s largest automakers, global tire brands, and aftermarket part suppliers. Dissatisfied with the corporate world and resentful of having to wear suits everyday, he pivoted to writing about cars. Since then, that man has become an ardent supporter of the right-to-repair movement, been interviewed on the auto industry by national radio broadcasts, driven more rental cars than anyone ever should, participated in amateur rallying events, and received the requisite minimum training as sanctioned by the SCCA. Handy with a wrench, Matt grew up surrounded by Detroit auto workers and managed to get a pizza delivery job before he was legally eligible. He later found himself driving box trucks through Manhattan, guaranteeing future sympathy for actual truckers. He continues to conduct research pertaining to the automotive sector as an independent contractor and has since moved back to his native Michigan, closer to where the cars are born. A contrarian, Matt claims to prefer understeer — stating that front and all-wheel drive vehicles cater best to his driving style.

- Lorenzo It looks like the curves are out and the boxy look is back. There's an upright windscreen, a decided lack of view obstructing swoop in the rear side panels, and you can even see out of the back window. Is Lexus borrowing from the G-Class Mercedes, or the Range Rover?
- Lorenzo Didn't those guys actually test drive cars? I was told that one drove like an old lady, another like a maniac, and the third like a nervous middle aged commuter who needs to get to work on time and can't afford big repair bills, and they got together to pass judgement within their individual expertise. No?
- Lorenzo Aw, I don't care what they call the models, as long as they don't use those dots over the O's.
