1. A method for determining a distance driven by a vehicle, comprising:
at the vehicle, determining a speed of the vehicle;
when the speed of the vehicle is above at or above a first speed threshold value, sampling the location of the vehicle at a first rate;
when the speed of the vehicle is below the first speed threshold value, sampling the location of the vehicle at a second rate such that sampling at the second rate occurs more frequently than sampling at the first rate;
recording each location sample to produce a location record comprising a plurality of location samples; and
determining distance driven by the vehicle by summing the distance offsets between successive location samples of all of the plurality of location samples.
