text: People tend to buy less cars if you limit car usage. The less cars you buy means the more money you save. According to "The End of Car Culture" by Elisabeth Rosenthal a study found that driving by young people decreased 23 percent between 2001 and 2009. The people who drove less between that time must have saved alot of money on gasoline. When you don't use your car as much it ends up benefiting everybody.
