When I look back to when I was working at a restaurant in high school, I remember wishing I had a car. But truth be told, even after a 5 - 6 hour shift after school, most nights I found the short 5 mile ride home rather relaxing, even enjoyable.
But as noted in many posts, Commuting by bike may not be the best choice for many folks. I'm thinking of the people who don't have an excuse and won't even bother to give biking a chance.
