Automatic Emergency Brakes Fail 4 Out of 10 Times After Dark

AAA found that many pedestrian emergency braking systems still struggle to detect people at night, especially those in high-visibility clothing.

đź“… Today's Story: A new AAA study revealed that despite improvements, Pedestrian Automatic Emergency Braking (PAEB) systems still fail to detect walkers 40% of the time in nighttime conditions, even under ideal scenarios.

đź“° What Happened: Testing at 25 mph, AAA researchers found that even modern Pedestrian Automatic Emergency Braking (PAEB) systems had serious shortcomings. Required on all new passenger cars by 2029, PAEB systems failed 40% of the time at identifying pedestrians in low light. The high-visibility gear worn by construction workers and first responders even confused some systems in the dark.

🔍 A Closer Look: Some models, like the Toyota Camry, outperformed at the test. However, even the best performers couldn’t detect dummies consistently after hours with automatic systems. The findings suggest that PAEB testing standards, which rarely simulate real-world night conditions, aren’t pushing automakers to address these deadly blind spots in a practical way.

đź§  Why It Matters: With over 7,000 pedestrians killed in 2023 (77% at night), the ongoing pedestrian death crisis demands more than the tech equivalent of band-aids. Researchers are urging regulators to strengthen automatic testing protocols and encouraging cities to adopt safer road design and infrastructure, rather than relying too much on future automations.
