It has seen the construction of 118 miles of bicycle paths, the most of any Latin American city, according to Mockus, the city's mayor" (Selsky, Paragraph 27). "As a result, 70 pecent of Vauban's families do not own cars, and 57 percent sold a car to move here. "When I had a car I was always tense. I'm much happier this way,"" (Rosenthal, Paragraph 3). "It was the third straight year cars have been banned with only buses and taxis permitted for the Day Without cars in this capital city of 7 million" (Selsky, Paragraph 21). "Vauban, completed in 2006, is an example of a growing trend in Europe, the United States and elsewhere to separate suburban life from auto use, as a component of a movement called "smart planning""(Rosenthal, Paragraph 4). Finally "the rise in cellphones and car-pooling apps has facilitated more flexible commuting arrangements, including the evolution of shared van services for getting to work" (Rosenthal, Paragraph 35).
