text: One thing that could be a good way to start this "Limited Car Usage" would be what the city of Bogota, Colombia is doing: The Day Without Cars. This is promoted as a program when in that day cars are banned with only buses and taxis permited. This inspires the people to walk more, ride a bike, and if something is very, very far they could just take a bus or a taxi. This would make a great impact on people's life and maybe it would soon be joined by other cities or whole countries like the cities of Cali and Valledupar have already done.
