text: In conclusion, although living in a world free of cars is a world many of us can never dream of, it has shown to lead to significant advantages towards traffic, pollution, and the overall community, which can be seen in the cities; Vauban, Germany, Paris, France, Bogota, Columbia and the United States -- as stated in the sources "In German Suburb, Life Goes On Without Cars," "Paris bans driving due to smog," "Car-free day is spinning into a big hit in Bogota," and "The End of Car Culture." Many of us should no longer dread the banning of cars, but anticipate it.    This would not be denifical in a classroom because it would make students uncomfortable knowing something is watching them, this would need its own computer to run, and it could not handle 30 people at a time.
