I commute via bicycle. From my experience, and after hearing the opinions of some coworkers, there are some other reasons more people don't do it: 1. It takes more time. There are certainly situations where bicycle commuting saves time (see: New York city or the like). There seem to be far more places where cycling will double or triple your travel time, especially considering the time needed to shower/change at the end. Which leads me to: 2. Lack of shower facilities. I am lucky enough to be able to shower ofter the ride; many aren't. Yes, I know the argument of "you don't need special clothes to bicycle, do it like Denmark, yadda yadda". This may be true in Denmark. My area is hilly enough to make you sweat. Also, if you go fast enough to try to minimize the time issue above, you sweat. Also, it's not comfortable to me to be biking in my work clothes so I have to change anyway. 3. Grooming concerns. It's not easy for women to put on makeup in the typical work/gym bathroom. It's also a problem (at least it takes a while) for anyone with longish hair to get it styled after it's been in a helmet or been windblown and/or been washed. And only the most devoted are going to change their hairstyle just so they can bike to work or something.
