The driving has decreased 23 percent from the years 2001-2009. That shows you that America's attachment to cars has decreased. The number of miles driven in the United States peaked in 2005 and decreased afterwards. The number of miles driven per person was about 9 percent below the peak and equals to where the country was in January 1995.
