Do people like me do things like this? This is a question that we all ask ourselves.

San Francisco has figured out a creative way to answer this question. Walk down Market street and see the meters that show how many bikes have passed that point. For the aspiring bike commuter, this is social validation that yes, people like her bike to work. 

As a bonus, it also taps into our desire to leave our mark. Every trip puts another drip in the bucket, a visible symbol of our presence.
