i've done my share off pisseed off smoke rolls, but just be ready to head your butt to jail for a long time if something bad happpens. Once you go too far then you realize what Y-knot is saying. Y-knot did go too far in putting down the thread starter, but i think he may realize what can happen. The more poeple that smoke others out, the more the general public will be upset. I've personnal seen people start wrecks and almost throw the whole I 15 into a big mess. Others safety needs to be remembered before you get ****** off and smoke others out. On the other hand, if you can see through the smoke, then i don't think its that bad. Now, when i get upset at a driver and feel the need to "turn his day into night", it's usually done on a country road and not on a big hiway were everybody can see it. Every situation is different.
