Miles per gallon

Every time I tell someone that I get 100 mpg and travel 10 miles a day on my scooter people focus on the 100 mpg. "1 gallon every 2 weeks" also seems impressive. Upon reflecting on it, the main benefit is really the low mileage that I travel. I travel very low mileage. I travel 10 miles per day, commuters from the suburbs travel at around 50 miles per day. Even at 100 mpg, they are still using 10x the amount of gas that I am. I know that everyone can not have such a short commute, but it seems that one way to reduce the gallon/$GDP would be to work on making work closer to home.
