RESEARCH - Adaptive Cruise Control Encourages Speeding

IIHS LogoAccording to a study conducted by the Insurance Institute for Highway Safety, drivers are substantially more likely to speed when using Adaptive Cruise Control (ACC) or automations that combine ACC with lane centering than when not using either technology. The concern here is that abuse of the system will cancel out the safety benefit of having it.

The study found that drivers who traveled over the posted speed limit using ACC chose a higher speed than those who traveled over the limit without ACC. This finding happened most often on roads that had limited access and a posted speed limit of 90 km/h.
