Sorry Mike, that just plain does not work in the USA, because the average person has total disregard for everyone else on the road. I have never had someone get over when I flashed them. I never tailgate, unless it is on purpose after I have been cut off, or someone has done something else dangerous to me. Nobody here has lane discipline, most Americans would have their licenses revoked after a week driving in Germany.
Guy got a closed head injury and died a few days after a Kings game following an altercation in the parking lot concerning getting out of the lot last week. The police are not pressing charges as they say it was a "consensual fight" which seems a little insane to me. So if someone attacks me, if I fight back they can kill me and get off, that just seems wrong.
