The invention provides a system for analyzing and evaluating the performance and behavior of a driver of a vehicle, and for displaying the results of the analysis and evaluation. A vehicle sensor utility is used to monitor the state of the vehicle while being driven by the driver. A raw data stream from the vehicle sensor utility is input to a driving event handler that detects driving events in the raw data stream and outputs to a maneuver detector a driving event string. The maneuver detector is configured to recognize patterns of driving maneuvers. One or more ratings of the driver's driving performance are calculated based upon the driving maneuvers as executed by the driver. The ratings are displayed on a display.
