Well my take on this (air pollution stickers) is
The French must be one of the worst offenders for pollution due to there crazy roads
There are more speed humps in France than most places forcing traffic to brake then accelerate...
This is going to have a massive effect on emissions
Then to top it off you now have a random ( fucking dangerous IMHO ) give way to minor roads joining main roads system causing even more stop starting
Having seen 40 tonne trucks hauling the brakes on then accelerating flat out back up to speed on a main road to give way to a minor road is madness
The French may like to do things differently...But
