text: Paris is being polluted by cars which is making the air fog up. So in order to regain control of the air, they have to ban cars temporarily. On mondays cars with even numbered license plates were commanded to to leave their cars at their house or get a 31 dollar fine. The uneven numbered license plates would get the same fee the next day. 4,000 people were fined for driving on the wrong day. Since the banning of the cars, Paris was down 60% of smog/fog.
