The International Herald Tribune has a great article today about the rapid spread of bicycle-sharing in Europe.  I could be wrong, I think the growth of these programs is a clear signal that the European commuter “gets” the multiple benefits.  They can save on costs for the vehicle, the fuel, the parking and the servicing and they can reduce carbon and other emissions while benefiting their own health.  Barcelona alone has added 80 miles of new bike lanes in the last 2 years.  Places like Chicago, Boston and New York that are still studying their options need to get with the program.
