Aw, now, don't be offended if you're not part of the problem!  I have diesel vehicles as well.

I also see newer trucks belching (anything made in the last ten years should be free of black smoke) on a daily basis.  If these owners had the emissions systems in place, the trucks could not do this.  If emissions inspections were still in place, they owners would be far less likely/willing to perform "deletes."  The owners who do this stuff give all of us a bad name and perpetuate the myths about diesel.  :(
