1. A method of operating a motor vehicle including an electronic control unit, the electronic control unit being configured to perform the method comprising the steps of:
- determining a first location of the motor vehicle, the first location corresponding to a first portion of a roadway segment;
measuring a value of a first state of charge of a battery at the first location;
measuring a value of a first fuel level of a fuel tank at the first location;
determining a second location of the motor vehicle, the second location corresponding to a second portion of the roadway segment that is different from the first portion;
measuring a value of a second state of charge of the battery at the second location;
measuring a value of a second fuel level of a fuel tank at the second location;
submitting the first state of charge value, the first fuel level value, and the first location to a service provider; and
submitting the second state of charge value, the second fuel level value, and the second location to the service provider; and
wherein the service provider is configured to determine a difference between the first state of charge value and the second state of charge value and a difference between the first fuel level value and the second fuel level value for the roadway segment between the first location and the second location.
