1. A method for monitoring fuel status of a vehicle having a fuel tank, the method comprising the steps of:
- determining an amount of fuel in the fuel tank;
obtaining a geographic location of the vehicle;
obtaining a service station density measure corresponding to the geographic location;
calculating a fuel threshold based at least in part on the service station density measure corresponding to the geographic location; and
providing a low fuel indication if the amount of fuel is less than the fuel threshold.
