I was a little surprised to read that Mark Martin emplyed this tactic in his duel with Juan Montoya near the end of the Loudon race. See this article: http://www.thatsracin.com/115/story/18965.html Usually, I don't like the "bump and run" and have been critical of it. But this incident shows another side. If a leader pulled this tactic on me and I got back to his bumper, or if I was close to him in a later race, I'd bump him in an instant. What say you?
