Been to budapest last year the air there smelled of cigarette smoke way too much of it. Other European cities have cleaner air.

Just as note, people underestimate the pollution volume from cigarettes, because they are small I guess, but since millions are smoked every day in countries like France, it makes a lot

I estimated that PM2.5 pollution from cigarettes can represent up to 5% of vehicle traffic pollution (estimation made for Paris, using their data of traffic pollution, and cigarette sales)

Also, when someone is smoking in his idling car in traffic jams, there's actually more pollution coming out from his cigarette than from the rest of the car (cf that old paper https://www.newscientist.com/article/dn6312-cigarettes-more-...)

Of course it's just one factor among others, but each of them is worth efforts

Not sure about the downvotes, but I live here for more than a decade and I agree. The city is very car friendly and not much was done to mitigate this. At least we have a new mayor now who's somewhat likely do do actually something.
