So to give you other example. You live and nearby opens a chemical plant and starts smelling, so you just buy gas mask and hazmat suit or start complaining?

And yes other means of transport also does pollute, but amount is is critical here. You need much less public transport than you need individual cars.

I perfectly understand that there is no quick solution (only quick patch with air purifier) so thats why we should not normalise this and remember to complain (after buying air purifier)

I got tired of that sort of argument when I realized that a great many of the people who argued that they have the right to tear down the side streets of walkable downtown neighbourhoods lived in unwalkable suburban neighbourhoods. Those unwalkable neighbourhoods were usually designed with a single access road to ensure there was no through traffic, so they would never have to deal with that problem. Then those same people had the audacity to ask everyone to pay for additional access roads when they realized that a single access road was a disaster when their neighbourhood needed emergency services and had to be evacuated (because it was burning to the ground). Of course, those additional access roads had to be designed to discourage through traffic.

Am I bitter about that? Yes. There is nothing wrong with wanting the best for you. There is something dearly wrong with using what's best for you to make life worse for others.

Cant hurt to buy the filter and also lobby for safer transportation
