Advanced Driver Assistance Systems Get Better, But Drivers Are Still Needed

Crashes may be less frequent as the technology improves in collision avoidance systems, but the impact of partially automated driving remains murky. When advanced front crash prevention systems were combined with adaptive cruise control, there were large reductions in the frequency of property damage liability and bodily injury liability claims. However, when lane centering systems were also added, they had little impact.

Those are the highlights of a new study released earlier this month by the Highway Loss Data Institute (HLDI), a nonprofit affiliated with the Insurance Institute for Highway Safety that is financed by the insurance industry.

The recent analysis compared insurance claims data from various BMWs for model years 2013-17. Based on a total sample size of nearly six million insured vehicle years, the institute called it “by far the broadest examination” to evaluate the impact on insurance losses of systems that combine speed control with lane centering.
