Bunch of it is in my lungs too I assume from my days driving trucks, you could see the black rubber dust getting kicked up off the pavement at truck stops when it hadn’t rained in a week. Not surprising to me that rubber dust is a particularly prevalent and pervasive pollutant. Also as someone who go karts often you get absolutely covered in it.

This is one of the biggest bummers about trying to be a responsible car enthusiast and track driver to me, there’s no real good way around it, and I’m a worse offender than most chewing through sets of soft performance tires.

The only good solution is fewer road vehicles because nothing will replace rubber and plastics for tires, though maybe the compounds can be made less damaging in general that’s not going to really solve the issue and it will be made worse with heavy electric vehicles.
