text: Limiting car usuage come along with many advatages. One advatage of limiting car usage is that you can limit the amount of smog that goes into the air and also into your lungs. In source 2 it says, "After days of near-record pollution, Paris enforced a partial driving ban to clear the air of the global city. On Monday motorists with even-numbered license plates were ordered to leave their cars at home or suffer a 22-euro fine($31)." That is a very good choice of action because without hearing that they would have any concequences people still would have drove their cars. In source 2 it also says, "Congestion was down 60 percent in the capital of France, after five-days of intensifying smog..." So, by limiting car usage just by the even numbered license plates there was less smog in just one day. In source 2 it says, "The smog cleared enough Monday for the ruling French party to rescind the ban for odd-numbered plates on Tuesday." So, the success of just one day made people want to do it a second day with just the odd-numbered license plates. If they keep this up and eventually have a day where neither odd nor even numbered license plates can drive the smog will eventually clear all the way up.
