Bicycling is pretty popular too (and drivers are more respectful there). So you don't even need to be dependent on rail so long as you live within some single digit kilometers of work. To give you a concrete figure, I live in Manhattan and have a cross-town commute (i.e. takes longer than an up/downtown commute of similar length) of 3 km that takes 10 minutes. I could easily do a longer commute no problem, and it might even be good for me since I'd get more daily exercise.
