No, many people won't. Think of how many times someone on this forum has said something about cutting off their cats or deleting their EGR.
I just responded to one of those.
While I agree that there's always going to be people out there who don't care about the environment in the slightest, I think it's reasonable to assume that most auto enthusiasts are reasonable people who would be inclined to stick to a set of rules and regulations if it weren't absurdly one-sided. There are going to be people who break the rules no matter what they are, it's just easier for them to convince themselves that it's OK to do so when the rules are ridiculous.
The auto hobby is becoming the scapegoat for the gross polluters.
I agree with this 100%. It's sad, but it is what it is.
That said, let's chill out on the political side of this discussion. I know that's easier said than done with a subject like this, just don't want the thread to spiral in that direction.
