170,000 miles a year dealing with that stupidity and much, much worse!!! The best advice I ever got concerning controlling road rage, "when someone cuts you off, drives slow in the left lane or any other act of idiocy on the highway, imagine that person is your beloved family member or friend, be patient, just shake your head and go on. Regardless of who they are, they fit that criteria for someone. It's really not worth getting in trouble over." Since receiving that advice and following it, driving has become a whole lot less stressfull. Hope this helps,
Josh
