A new study shows the average American commutes an average of 25 minutes. That's almost nine full days a year behind the wheel. Commutes have worsened over the last two decades because highways haven't kept pace with population growth and urban sprawl. If you work in New York City, your average commute is the worst in the country: almost 36 minutes long. For the nation's easiest commutes, you have to turn to the colder climes of Omaha and Buffalo.
