"Rolling coal" doesn't impress me and never will and those who do it are imbeciles of the first order. The EPA, be it federal or state, has acquired entirely too much power and needs to be reigned in or abolished in its entirety.
This whole BS of emission control was was started in commiefornia in the early 60's to fight smog in the LA basin. Funny thing though is that gasoline powered vehicles were far from the main cause, if you ever were behind an LA bus in the 60's you'd know from where I speak. When those buses would start from a standing stop the noxious smoke they emitted could kill mosquitos in a 2 mile area.
I rather feel sorry for the guy, but buyer beware comes to mind in his case.
