text: Another big problem in pretty much all countrys is congestion of their inner streets. When streets have major traffic alot of things change including the mood of people,and there is a higher percentage of car crashes. To fix this problem many cities did pretty much the same as before to retrict cars on certain days. A brilliant idea was presented and used in Paris. The idea was that "on Mondays motorists with even-numbered license plates were ordered to leave= their cars at home or suffer a 22-euro fine ($31), The same would apply to odd-numbered plates that following day". After this brilliant event finished congestion was down sixty percent in the capital of France, and after five days the smog was gone.
