1. A method of determining a rating of a driver comprising:

  • collecting, by at least one sensor, input data comprising;

    current road data, current speed and current acceleration, for a vehicle being driven by the driver;

    assigning the current acceleration to one of a plurality of speed bands, based on the current speed;

    storing a specific database and a collective database, wherein the specific database comprises prior acceleration data of the driver, and the collective database comprises prior acceleration data representing a plurality of sample drivers driving same type of vehicle as the vehicle during prior driving trips,wherein both the specific database and the collective database include, for each of the plurality of speed bands, a mean acceleration and an acceleration standard deviation (SD) of their acceleration data;

    comparing, by a processor, the current acceleration with a weighted-acceleration, the weighted-acceleration comprises weightings of;

    the current road data,the mean acceleration and the acceleration SD, of the current acceleration assigned speed band, of at least one of;

    the specific database and the collective database;

    based on one or more of the comparisons, determining, by a processor, a driving style rating for the driver; and

    displaying the driving style rating.
