Do these things actually contribute meaningfully to air pollution? I think "rolling coal" is silly because it's so childishly spiteful, but I've rarely actually seen it.
Loud cars and motorcycles seem to be everywhere.
It’s a regional thing I suspect. It’s a big problem in utah, home of the Diesel Brothers and some of the worst air pollution in the country. It’s just recently illegal here.
One guy doing it might not be that meaningful but, that’s true of just about everything.
