I'm not saying give up ground on the sport, but we have to face the facts, taking that stuff off trucks for on the road (public road) is breaking the law. Even though it isn't that bad we can't flaunt it. Just like when I see some retard acting stupid with a gun, it enrages me. Public opinion right now isn't what is used to be. We need to replace the image of a drunk redneck waving a gun shooting random shit and blowing smoke everywhere to someone that is responsible, a gun owner that is well trained and responsible striking fear in criminals not random people. Performance diesel owners pushing power while keeping daily driving tunes clean (even though the nox levels are up if you can't see it most don't care).
The average American is stupid and entitled. They feel they have the right to say whatever they think and what they think is important, even though it was based on 0 knowledge on the matter. I can't tell you how many people tell me how aircraft should be made safer (i.e. cable news) when they couldn't even understand how to start the airplane or things a basic student would know. But that doesn't stop them from trying to force their retarded ideas on others.
SO, to end this rant, the EPA is influenced by public opinion like any other govt org (since they report to elected officials who report to the masses for reelection). You go blowing smoke in an intersection, you piss off the hippies that much more (maybe even win by pissing of a congress man himself with smoke). They start bitching, and when people bitch the govt has to keep them happy. And they see the smoke so that has to be so much worse to the air than nox in their mind and that is all that matters. So hold the ground, fight the EPA when it is BS, but don't be a retard and ruin it for the rest of us by destroying what little public opinion is left of the sport
