Pragmatically my car gets me places faster than my bike in most cases. Yet because it requires registration and insurance in addition to expensive repair bills I find that I feel trapped by the need to have access to a car. This is one of the reasons my wife and I keep it to one car and I mostly commute by bike. The fact that I don't need anything other than my bike to get across town feels freeing. I don't worry about my bike starting in the morning. Worst case scenario, say a badly cracked frame, I'm a few hours on craig's list, and $150-200 away from being back on the road. Hopefully with an awesome new 80's or early 90's era work of chromoly or lugged columbus steel. This simplicity is part of why I find cycling to be an act of embracing my freedom. I also associate cycling with being 10 in the suburbs of Chicago and the freedom and independence my first dirt bike gave me. The freedom to go to the movies without my parents, to go to the pool in the summer and hang out with my friends all day eating lousy concession stand pizza and drinking way to much Dr.Pepper. The freedom to take myself to school without the bus, and stop at the bowling alley on my home in the afternoon. Every time I ride my bike to work now as an adult I get to experience just a touch of that feeling of freedom I experienced as a young kid. I fear that feeling would be lost if I needed to carry proof of insurance with me. Let the cagers carry the insurance and registration as they pass furiously trying to change into the lane that they are sure is gonna get them there a little quicker, and relieve them from the prison of a deadlocked rush hour highway.
