Bike commuting is just too much fun. For me, my commute by bike is hardly longer than by car. Parking is atrocious with a car. By bike, I can take advantage of a secure bike rack with video surveillance or I can take my bike to my office if it is raining. For me, cycling is a no-brainer. Sure commuting by bike may have some inherent risks, but so does commuting by car and so does being a pedestrian in a cross walk with the "walk signal". Cars come close to hitting me fairly frequently when I am in the cross walk (just walking) when I have the signal. It is absurd. It should also be added that being sedentary poses health risks, as well.
