After enrolling in OnStar Smart Driver, customers with eligible vehicles receive ongoing driving behavior feedback, such as hard braking, hard acceleration, late night driving, distance driven, time spent idle, speeds over 80 mph, average MPG and average MPH, as well as helpful tips to enhance their driving skills. This is compiled into an overall OnStar Smart Driver score, which can be compared anonymously against other drivers enrolled in the service. ©️ General Motors
