An early crop of advanced crash avoidance technologies includes some clear success stories when it comes to preventing crashes, insurance claim analyses by the Highway Loss Data Institute (HLDI) show.
Forward collision avoidance systems, particularly those that can brake autonomously, along with adaptive headlights, which shift direction as the driver steers, show the biggest crash reductions. Lane departure warning appears to hurt, rather than help, though it’s not clear why, and other systems, such as blind spot detection and park assist, aren’t showing clear effects on crash patterns yet.
HLDI analysts looked at how each feature affected claim frequency under a variety of insurance coverages for damage and injuries. Clear patterns were seen in claims under property damage liability (PDL) insurance, which covers damage caused by the insured vehicle to another vehicle, and collision insurance, which covers damage to the insured vehicle. Frequency is measured as the number of claims relative to the number of insured vehicle years. An insured vehicle year is one vehicle insured for one year, two vehicles for six months, etc. The model years of the vehicles included ranged from 2000 to 2011, depending on when an automaker introduced a feature. Insurance data through August 2011 were used.
