theoretical gallons of gas is not useful when you have vastly different ranger per gallon (or kilowatts) of energy. Reporting miles of range is what makes sense

theoretical gallons of gas is not useful when you have vastly different ranger per gallon (or kilowatts) of energy. Reporting miles of range is what makes sense. Cars get less mileage when they 70 miles per hour than 60 mph, but its not so visible because you don't ever have such an exact measure of gas and range available.
