text: Another good reason to limit car usage is to bring together community. There is a city in Germany by the name of Vauban (according to a source by Elisabeth Rosenthal,) which completely bans driving cars. Inhabitants of this community walk or bike everywhere, which is also a good form of exercise that one could do in order to stay fit. The city was designed with walking in mind, and everything is close by as a result. If we were to have more of these communities, then green house emissions could be greatly lowered.
