Interesting article. When I read about the numbers and percentages for bike travel I'm amazed and impressed. It seems that transportation in larger cities and towns has been a problem for a very long time; I remember reading an article about the problem of traffic congestion caused by horses and wagons with the associated pollution problems and chronic shortage of parking. I think bipedalism will be the only mode of transportation that doesn't have some type of problems associated with it....unless you start worrying about where everyone would park their walking shoes.
