There's is also pulling out an actual source rather than hand waving conjecture based on random opinion pieces. https://www.bts.gov/content/estimated-national-average-vehicle-emissions-rates-vehicle-vehicle-type-using-gasoline-and https://www.bts.gov/content/estimated-national-average-vehic... Gasoline cars 2020: Exhaust 0.005 g/mile. Brakes 0.003 g/mile, tires 0.001 g/mile. So exhaust + brakes produce 8 times as much PM2.5 as tires. So the argument but 'but but EV's are heavier and produce more PM2.5 than gasoline cars' doesn't cut it. Also I've seen references that show natural gas heating isn't nearly as clean as portrayed.
