A growing body of evidence suggests that modern driver assistance technologies are significantly reducing road crashes, and new research into Mazda’s 2015 to 2023 models highlights just how powerful these systems can be when combined.
A recent analysis by the Highway Loss Data Institute (HLDI) finds that as advanced driver assistance systems become more sophisticated and more widely fitted, their safety impact grows accordingly. The study examined six bundles of features as well as several stand-alone systems across a range of Mazda vehicles, comparing changes in insurance claim frequency to measure real-world effectiveness.
Larger feature bundles prove far more effective
At the simplest level, the basic package consisted of front automatic emergency braking. This system, which also included forward collision warning, already delivered clear benefits: a 13 percent reduction in property damage liability claim rates and a 9 percent reduction in bodily injury liability claims.
However, the real gains emerged in the more comprehensive packages. These added features such as pedestrian-detecting automatic emergency braking, adaptive cruise control, high-beam assist, lane departure warning and prevention, rear automatic emergency braking, and a driver attention monitoring system. Because these bundles were offered on newer vehicles, they also included upgraded versions of earlier technologies.
The most extensive bundle was linked to a 39 percent reduction in property damage liability claims and a 21 percent fall in bodily injury liability claims. Although the latter figure was not statistically significant, the trend across all bundles was clear: the more technologies included, the larger the reduction in crash-related claims.
One feature did not create additional benefit. The inclusion of Driver Attention Alert had no measurable effect, likely because it only activates under specific conditions, such as prolonged driving at certain speeds and on roads with clear lane markings.
Pedestrian detection and rear braking deliver notable improvements
Two features stood out for their substantial contributions. Updated front automatic emergency braking, now with pedestrian detection, not only prevented incidents involving vulnerable road users but also appeared to better mitigate collisions with other vehicles. Rear automatic emergency braking also produced large reductions in claims by preventing common low-speed parking impacts, which account for a considerable proportion of insurance reports.
