text: Along with promoting a healthier lifestyle, limiting car usage can also help the U.S. withone major problem. Over the years the U.S. has had many great presidents,but almost all of them have promised the same thing, that they will reduce our dependence on foreign oil. But nothing has happened. I believe that limiting car usage will help us in reducing the United states' dependence on foreign oil because if we aren't driving our cars as often we won't need as much oil.
