text: Paris, France has been forsed to stop using there cars ever once in a while due to all the smog in there city. in Source 2 it is stated that, "... Motorists with even-numbered license plates were ordered to leave there cars at home or suffer a 22-euro fine($31). The same would apply yo those Odd-Numbered plates the following." this is telling you that there city was so bad tha the goverenment was forsed to have ther city be taxed if thet wanted to drive ther car. Normally paris has more smog then other places in europe. some dilevery companys were mad at paris due to there lost revenue. Although cars that could be plugged in, hybrids, and cars carring three or more people were allowd.
