According to the first resource giving to us "Passenger cars are resonsible for 12 percent of greenhouse gas emisiions in Europe ... and upto 50 percent in some car-intensive areas in the United States." But people are saying its a good idea to ban cars. Heidrun Walter states that "When i had a car i was always tense, i'm much happier this way." So to some people there are advatages of limiting car use.
