text: As well as car resricted subburbs some cities have other ideas to reduce car usage. Paris had previously installed a plan to have drivers with even numbered license plates to leave their vehicles home and odd numbered plates to leave their vehicles home  the next day "Congestion was down 60 percent". This shows that this idea to ban vehicals based on license plates can work, however 4,000 people were fined due to non cooperation. Paris was not the only capitol to try and lower personal vehical usage, Bogota, Colombia for three years has had a day in which cars have been banned only allowing taxis and buses, the goal is to reduce the smog in a capitol city of 7 million. Despite a rainy day most citizens participated in the car free day "It's a good opportunity to take away and lower air pollution" stated by Carlos Arturo Plaza. Foregin cities and countries aren't the only ones trying to lower pollution, "recent studies suggest that Americans are buying fewer cars, driving less ang getting fewer licensences as each year goes by." Although riding a bus or other public transportaion or an alternative to a gas or diesel vehical such as a bicycle may take longer than a car but it has shown to be worth the extra time.
