151 smog.... does it just happen here

is it just here or are the same problems occuring in the uk..... all cities now have these monitoring stations and thru out the winter there have been various traffic restrictions imposed in various areas including rome... all the northern cities... and even ancona... they have odd/even days during the week and complete bans on sundays...

the one oddity is that most of the southern italian cities dont seem to have the problem... or at least i havent seen them mentioned on the news.... which sometimes ignores everywhere outside of milan or rome anyway... a bit like the southern/london syndrome in the uk.....

the problem with traffic here i would say is no worse than the uk.... the pollution levels due to some theorists...is the amount of two stroke two wheeled vehicles.... they have very dirty emmisions....lack of servicing... and controls...i think the mot equivalent is still only every two years...

anyway is this happening everywhere or is it just in italy....and what happens in the summer when the air is still ....
