True however we generally talk about everything. Taking personal responsibility for for the impact your vehical can have on the environment should always be a topic of thought. Its why most of us would never purposely dump oil, gas other automotive fluids into the soil. Purposely running with out catalytic converters is the same deal. Especially if your only reasoning is half a hp. Or the unwillingness to spend a few dollars to keep your vehical properly maintained. Both of wich are not acceptable reasons. Also to bring this topic and question back up after, being admonished once before, and having posts alterd, just shows an unwillingness to follow rules put into place.
