text: Finnaly, not driving can reduce traffic in heavly populated areas. In paragraph 14 it shows how not driving can reduce traffic, "Congestion was down 60 percent in the capital of France, after five days of intensifying smog." In just five days traffic was down 60 percent! Imagine what a few car-free weeks or months could do. Again back to Bogota, Columbia, paragraph 20 states "...Millions of Columbians hiked, biked, skated or took busses to work during a car-free day yesterday, leaving the streets of this capital city eerily devoid of traffic jams." This shows that car-free days can even be done in large cities.
