I'm kind of a "to each their own" sort of dude, that was always my angle of opposition to the rolling coal stuff, it was just like walking past people telling them to fuck themselves. If you want to do it out on your own, that's fine I don't care, but damn it's some dick ass bullshit when they opt to act like that while we are stuck in rush hour traffic. Way to fucking stop so you can roll coal for 15 feet just to slam on your brakes again, and well, it doesn't bode well for them not driving like jerkoffs during the remainder of the time.
We just don't really enforce any laws here, if you don't have plates and they won't chase, you can skip all the emissions test you want. We are fond of skipping the catalytic converter as well...but that's because they keep getting stolen.
