For me, commuting grew out of utility cycling. I started using a bicycle to run errands (grocery store, library, etc.) after work and on weekends, but was still driving to the office. I decided to try bicycle commuting for the first time on Aug. 25, 2005 and I've kept at it ever since.
In addition to the reasons other have already posted, I guess for me it boiled down to a realization that a bike was the right tool for the job. Using a 3,000 pound vehicle move me and my briefcase 2.5 miles to work everyday was like using a steamroller to press my shirts — they'd be wrinkle free, but an iron would be a better choice.
