21. Arrange a ride to work: Plan to share a ride with a co-worker, or take a bus, train or bike to work. You’ll spend about $5 less per ride (or $260 a year if you do it once a week).
22. Walk a mile: Chances are you run several errands a week right around the corner; use your car only for trips over a mile, and you’ll improve your health while saving on gas.
