text: Although people do want to benefit as individuals, it really comes down to the cost at the end point. But limiting car usage is actually not that expensive to the average person. In fact, by limiting cars, alternate transportation is promoted. Countries such as Colombia, have move on to bicycles. The major of Bogota(a city in colombia) said that due to the limitation of cars for a day "It has seen the constuction of 118 miles of bicycle paths". This is cheaper because the prices og bicycles are pale in comparison to cars. This means that transport would be so much more affordable. Now with the increase in bicycle travel, there would hardly be any large amounts of traffic. And although cars are much faster than bicycles, the fact that traffic will be a major factor in travel, bicycle travel will be more efficient. This ultimately means that by limiting car usage, transportation will be cheaper, and it will be just as efficient, if not more. It can be said that it would be difficult to manage bicycle travel, but David Goldberg, an offical of transportation for America said that in countries such as the U.S.A. 80% of appropriations have gone to highways. This ultimately sets the stone for the construstion of these lanes. By limiting car usage, these appropriations can be set aside for other means of transportation. Indeed in the end  Vauban is correct in calling this "smart planning".
