text: The ban of driving has also spread to Paris. Paris started off by banning any motorists with an even-numbered license plate, and the following day the same would apply to the odd-numbered plates. There was a descrease of congestion by 60 percent. France has a tax policy that favors diesel over gasoline, which lead to the blame of diesel for the intensifying smog in the city. Around 67 percent of the vehicles in France are diesel  compared to the 53 percent average of diesel engines in the first of Western Europe. With just the few short carless days, the smog cleared from the city and the ban was rescined a day after.
