alt Hacker NewsAll 550K diesels with modded emissions are not rolling coal, that is a wild extrapolation
I didn’t ask the multiplier of badness of a single individual doing a bad and stinky thing, I asked what you think the _scale_ is. Do you believe that all people with trucks modified to do this are doing it at all times? Or even half the time? How many people do you think are doing it?
I am absolutely certain that more people are rolling coal than are tinkering with their engine timings for benign performance reasons.
