System for evaluating driver risk, comprising a local V2X communication unit for transmitting at least one attribute from a self-vehicle to remote vehicles and for receiving in the self-vehicle at least one attribute from each of the remote vehicles, the self-vehicle and the remote vehicles having respective drivers, a local unsafe act detection unit configured to detect at least one unsafe act of the self-vehicle and to report the at least one unsafe act, and a centralized driver behavior-grading unit configured to process the reported at least one unsafe act, to grade the driver of the self-vehicle for risk, and to output a respective self-vehicle driver risk grade. A method performed using the system comprises checking if the remote vehicle had a major speed decrease in a recent given time period, if yes, checking if the self-vehicle influences the remote vehicle, if yes, checking respective speed patterns of the self-vehicle and of the remote vehicle for patterns typical for at least one unsafe act, if patterns typical for at least one unsafe act are found, grading the at least one unsafe act, and based on the grading the at least one unsafe act, grading the driver of the self-vehicle for risk.
