text: Now I'm going to talk about some evidence in the article that makes limiting car usage better for life. In source 1 "In German Suburb, Life Goes Without Cars", Heidrum Walter, a citizen from Vauban said that she lives happier without cars because when she had a car she was always tense (paragraph 3). Now in sourse 2 the article says that cold nights and warm days caused the warmer of air to trap car emissions(paragraph 15), and that is really bad. Also in source 2 again the last paragraph says that the smog cleared when they banned the usage of cars.
