My experience precisely. I started bike commuting 7-1/2 years ago thinking that I would ride 1-2 days a week, and it quickly turned into whenever possible. I really enjoy commuting on my bike, but I hate getting stuck in a car in heavy traffic (except during foul weather). Another big advantage is that bike commuting actually saves me time, even though it takes longer than driving. That's because I used to work out after I got home from work, which would take1-2 hours -- causing continual friction with my wife, who wants to eat soon after getting home.
