Smog in Paris. http://thinkprogress.org/climate/2014/03/15/3409951/smog-paris-public-transport/#
Public transport has been free there this weekend
Driving in Paris limited by alternate days for odd/even reg numbers
The French Automobile Association claim that it's not car driving that causes smog
...so I checked what causes smog, seems it's caused by popcorn packaging (and some other things)
