This is a bad-faith fallacy. We had cars that emitted X amounts of tyre/brake particulate and 10X amounts of combustion residue, we got rid of the combustion part, and now we hear "OMG! 100% is tyre particulate!!!"
Sure, but people won't stop moving, and there's no vacuum, you should compare brake particulate to whatever else people would use if cars didn't exist.
