Cell phones are great rage stoppers
I get angry at the stupid things that people do... a few times I have pulled out the cell and did a quick *FHP (Florida Highway Patrol) to report some moron instead of loosing MY cool. It makes me feel much better.
On one occasion that I saw the guy pulled over, out of the car, amrs out walking the line... of course I honked as I went by to ruin in concentration.
