Evidence: In the article "Car-free day is spinning into a big hit in Bogota" by Andrew Selsky, the changes that the Columbian city of Bogota has gone through in response to less car use are discussed. The changes are a direct result of the city's Day Without Cars campaign, where car use is banned for the whole city for one day out of a year. It reads, "It has seen the construction of 118 mile of bicycle paths, the most of any Latin American city, according to Mockus, the city's mayor. Parks and sports centers have also bloomed throughout the city;uneven, pitted sidewalks have been replaced by broad, smooth sidewalks; rush-hour restrictions have dramatically cut traffic; and new restaurants and upscale shopping districts have cropped up".  These additions are in response to the city's inhabitants using alternative transport. Since cars could not be used, the public had to get to where they were heading by other means. Bogota was able to use the situation to improve itself by either fixing things already in place or adding new ones competely. Another way that a city improved itself as a result of limited car use is shown by Elisabeth Rosenthal in her essay "In German Suburn Life Goes On Without Cars". She writes, "While there have been efforts in the past two decades to make cities denser, and better for walking, planners are now taking the concept to the suburbs". One of the results of applying this idea to suburbs is that stores are placed within walking distance of houses rather than in a mall next to a highway. Vauban, the city where the changes took place, is taking advantage of the opportunities to open new stores. This change would not only create more business for the strore itself but improve the economy of the city by increasing spending. The overall impact that limiting car use has had on citites is that it provides opportunity for the city to improve itself.
