text: In Bogota, Colombia, they have the "Day Without Cars" event, where only buses and taxis were allowed to use to roadways. THe "Day Without Cars" event has been going on since the mid-1990s, and it's part of an improvemenet campaign. If every cities in the entire world had a "Day Without Cars" event, that would generate a change to everyone at one time. Just imagine, one a year, to go a day without driving your car. The world would be a much cleaner and safer place without cars. People die everyday because of car accidents. We could change that with just one event each year.
