I wonder how a vehicle's utilization of it's cargo capacity could be included? For example semis and busses are down in the single digits mpg wise, but are far more efficient re: units of stuff moved per unit of fuel.
Note how I said UTILIZATION of capacity, as we all know (if we are willing to admit it) that the Suburbans and Expeditions of this country see more solo occupant duty than anything else.
