When being are more active throughout the day, occurences such as this are allowed to happen much more often. A day free of cars in Bogota left streets almost completely traffic free which in turn reduced smog and allowed for alternativ transportation.(Source #3). Cars allow us to ride through hundreds of miles with just the use of a few muscles. Running just 1 mile burns hundreds of calories and gets people feeling good. When people are fit and healthy, they feel better about themselves and have more confidence. The limitation of cars would allow this feeling to arise in thousands of people. People felt so good, they let nothing stop them; "The rain hasn't stopped people from participating," (Source #3).
