Kind of different, but kind of the same. I had an older asshat (yes I can call him that) catch me one time when I was leaving a restaurant with my kids, get nasty about my 35's on my Explorer. Kept telling me that they were illegal (according to his insurance agent) and he was gonna call the cops on me. My ex wife (wife at the time) worked across the foyer from the local PD and they all know what I drive, and ask about them all the time. I kept telling this jerk to go ahead and call the PD. He kept getting louder and more rude about it. I left, mainly cause I didn't want my kids to hear what I wanted to tell him ( I was thinking up brand new dirty words for him). Everybody's entitled to their opinion, thats why we live here, but when they get rude or obnoxious about it, its gone too far (main reason I don't go with the whole OWS thing). In my case, this old toilet shark had seen me a lot of days I didn't have my kids with me and he waited till they were with me, and thats what pissed me off the most.
As far as the "rolling coal" thing goes it is tacky and uncalled for. I have a 2003 Dodge with the cummins and even with a load of cows on it, it blows very little, if any smoke, plus Im pulling 24mpg out of it.
