Driver assists that help steer for you on the highway haven't contributed much to road safety, according to a new study from the Insurance Institute for Highway Safety and the Highway Loss Data Institute. That's in contrast to other features often bundled together as "advanced driver assistance systems," or ADAS, many of which have shown a marked reduction in crash and claim rates.
"Everything we’re seeing tells us that partial automation is a convenience feature like power windows or heated seats rather than a safety technology," said David Harkey, IIHS president.
However, we should note that, as a follow-up to a pair of earlier studies published in 2021, the new research by IIHS and HLDI focused on two older partially automated driving systems, model-year 2017–2019 Nissan Rogues with ProPilot Assist, and model year 2013–2017 BMWs with Driving Assistant Plus.
