1.) Loud shouting, including vulgar or violent references.
2.) Inappropriate hand-gestures.
3.) The apparent belief that the drivers/passengers in. neighbouring vehicles can hear the sufferer.

Joe: Be careful, that other car might pull out in front of you.
Bob: So what?! Let them! <Bob turns his attention to the aforementioned car>
Bob: COME ON! DO IT! I DARE YOU!
Joe: Bob. Drive.
