A computing device-implemented method includes receiving data representative of one or more travel parameters for distribution ranges for a vehicle that includes a first propulsion system, and, receiving data representative of one or more travel parameters for distribution ranges for a vehicle that includes a second propulsion system. The distribution ranges for the vehicle that includes the first propulsion system are equivalent to the distribution ranges for the vehicle that includes the second propulsion system. The method also includes receiving data representative of one or more travel parameters for distribution ranges for a collection of vehicles. The distribution ranges for the collection of vehicles are equivalent to the distribution ranges for the vehicle that includes the second propulsion system.
