Public Bikes in Paris - Velib

Paris has an extensive public bike share program, here is a picture of the bike station, you buy a pass, then you just puch in your number, grab a bike and ride, you can drop the bike off at any station.   The first 30 minutes are always free.   You will see lots of people using these bikes, even women and men dressed in nice business clothing, riding to their next appointment.   I was in San Francisco today, and saw that SF now has a very similar program, with very similar looking bikes.
