Depending upon where you're and how much the state wide acceptance of Global Warming, some places in the US are definitely heading towards that direction. Here in the Northwest, around the Seattle area, the statewide sponsor of bicycle is the biggest I've seen than any other states. There are bicycle lanes in most of the roads and many people bike to work,literally many. Bicyclist have pretty descent right and privilege here and every year the city and state legislature are making newer rules to promote alternative means of transportation. Their city buses are operated on vegetable oils, you can VAN POOL to work with your neighbor, get a FLEX car (shared kind of things, which I still have not understood). The mayor is a big supporter of Environment. They even have “Bike to Work” day People tend to be more green conscious and more healthy with lots of outdoor activities, which involves exercises.
