I totally agree. It's sort of like carrying a concealed firearm (or open carry when in AZ). You do not argue as any argument will be deemed an assault on your part when carrying a firearm. Just as you should just pull the hell over and let the jackass in the SUV pass.
But as a side note, since, when I'm not by myself, I am usually only riding with my girlfriend, if I was the survivor that guy would never make it to court.
