Report Finds Curves Throwing ADAS for a Loop

July 9, 2021—A recent study from the Insurance Institute for Highway Safety found curves in roads are posing challenges for ADAS features such as adaptive cruise control.

According to the report, ACC and other features such as lane centering were found to be disabled more often than not when driving around sharper curves, either because drivers switch the features off or because they're automatically deactivated. 

"We know that advanced driver assistance features may help prevent crashes, but obviously they can only do so if drivers use them,” says IIHS Senior Research Transportation Engineer Wen Hu, the lead author of the report. “This study suggests that these technologies will only be able to reach their full potential if drivers can trust them to handle curves.”

The researchers did not determine why the ADAS systems were deactivated in this study, but Hu says the information could help guide future developments in ADAS technologies.
