How many cars are in the United States? Take a guess. Answer is after the video.
There were 254,403,082 cars in the United States as of 2007. Did you guess correctly?
Here is an interesting table that shows the Number of U.S. Aircraft, Vehicles, Vessels, and Other Conveyances in the US from 1960 to 2007. The numbers paint an interesting picture. There are more than a quarter BILLION cars in the country now. There are only around 300 million people in the US. This is simply not sustainable. What we need to do at the local, state and national levels is promote the two most sustainable forms of transportation... walking and bicycling.
