I figure that by useing my motorcycle last summer for short trips around town, putting about 2,000 miles on it in total, I saved over $200 by getting about 25mpg more on a motorcycle then my car could get, if a moped, scooter, or electric bicycle can do even better, and act as a useful vehicle by having a rack, or a back pack for carring things, then your theoretical savings is even more.
