text: Also to some people a car is just a backup for when public transportation falls through. "They organize their summer jobs and social life around where they can walk or take public transporation or car-pool with friends." (Source 4) By reducing uneeded car usage we cause a more effiecent society less dependent on cars and more dependent on better types of alternative transportation. "'A car is just a means of getting from A to B when BART [type of public transport] doesn't work.'" (Source 4). By improving public transport we reduce car usage which improves the enviroment and quality of life.
