I bike to work. I highly recommend it. It takes me about 10 minutes longer in the morning, 5 in the afternoon. The difference is a bit more with low traffic, less (or even favoring the bicycle) with high traffic. For those 15 extra minutes daily, I get 2x25 minutes of high-intensity, low impact aerobic workout. I don't pay for gas. I have a dirt cheap car because I don't care about its gas mileage, etc. I can focus much better after the morning workout. I don't have to "sneak" anything. :) And: I can't get out of the afternoon workout. Gotta get home!
