> With modern emissions standards, more than 50% of the harmful pollution comes from tires/brakes/road surface wear/resuspended dust:

Sure, but what about compared to eg. 15 year old diesels with removed DPF filters? Those were the cars that were removed from paris (with the "eco stickers" and other regulation), and that brought the pollution down.

New cars exhaust very little particulate matter, so percantages don't say a lot.

I mean.. almost 100% of the polution of bicyles comes from tires/brakes/road surface/resuspended dust, but the total amount is very low.
