Front automatic emergency braking (AEB) systems have greater potential to save lives, but rear AEB is saving drivers the hassle and expense of many a fender bender, an updated analysis from the Highway Loss Data Institute (HLDI) shows.

Rear AEB was the standout feature in HLDI’s annual compilation of its research on the impact of crash avoidance technologies.

Researchers found that vehicles equipped with rear AEB had 28 percent fewer property damage liability claims and 10 percent fewer collision claims.

The updated rear AEB analysis added insurance data for model year 2015-18 Subaru vehicles with and without the feature to an earlier analysis of 2014-15 General Motors vehicles.

“We haven’t seen that kind of reduction in claims for vehicle and other property damage from any other advanced driver assistance system,” said HLDI Senior Vice President Matt Moore.

The impact of rear AEB on injury crashes was found to be relatively small.
