> I need to get my car washed; should I drive or walk to the car wash that is 100m away?

> Walking 100 m is generally faster, cheaper, and better for the environment than driving such a short distance. If you have a car that’s already running and you don’t mind a few extra seconds, walking also avoids the hassle of finding parking or worrying about traffic.
