For example, a suburban community in Germany, known as Vauban, has gone completely car-free. 57% of Vauban's residents sold a car to move in and, so far, the majority of them seem to be enjoying the benefits. Heidrun Walker, a media trainer and mother of two, is one of them. "When I had a car, I was always tense," she said, "I'm much happier this way." (Source 1) Walker's statement shows the improved psychological well-being of those who do not rely on cars for the majority of their transportation. Decreased reliance on motor vehicles can also improve the physical health of humanity. Without personalized vehicles for transportation, many people will walk, jog, bike, or skate to their various destinations. Such a phenomenon occurs annually in Bogota, the capital of Columbia. Every year, they host a "Day Without Cars", during which Columbians rely on their own two feet to move about their sprawling city.

If more countries hosted events similar to Bogota's "Day Without Cars", emergency rooms may find they have less clogged arteries to deal with.
