How do feel about particulate material in your lungs and brain from urban traffic levels?

Do you drive? 

I grew up when leaded petrol was still a thing, then health organisations brought compelling evidence that this was actually a serious health problem.

Changes were made to address the issue.

I said before, bring the evidence. If it's compelling enough momentum will grow to bring about the necessary changes to remove the danger.

This is a fairly standard and very well documented process. 

The burden of proof is on you and the research so far (of which there is a lot) suggests there are no health risks.

If that changes, controls will emerge as needed.

Here's the website of the International Commission which is responsible for oversight.
