text: In source one , in Vauban , Germany they are no longer using cars and instead are using alternative forms of transportation in this suburb. Heidrun walter a resident of this city talked about how he was "always tense" when owning a car which is true. It can be very stressful having to drive around and in the case of crowded areas have to sit in traffic for two hours a day. Another reason to get rid of your cars is the effects on the environment with 50% of carbon emissions in some parts of the US being blamed on cars. New laws in the US are also promoting the use of public transportation in the United States own suburbs giving suburban residents more of a reason to rid themselves of a car. In cities public transportation has been already implemented and can be much more efficent than driving around yourself.
