Collision warning systems reduce crashes. They may improve habits, if individuals avoid behaviors that trigger alerts. When paired with telematics, individuals may change behavior over concern about monitoring. Mobileye-630 aftermarket systems with multiple crash avoidance warnings were installed in 21 privately owned vehicles and telematics were installed in 15 of the 21. Warning rates were generated during 4-week baseline and 8-week treatment periods. Rates for three warning systems (forward collision warning, lane departure warning, headway monitoring) decreased by 30 to 70%. Rates were significantly lower for rural compared with urban drivers. Speeding behavior during treatment was similar to baseline. In a survey of participants, 62% agreed that Mobileye helped improve their safety while driving. Many drivers stated preferences for less conservative warning thresholds.
