Anti road rage

Its rush hour bumper to bumper traffic on the freeway. A truck pulls over on the shoulder in front of me, 2 guys get out and run behind my car and start pointing/motioning to a car behind me. Turns out there was a car in another lane that was stalled and they were trying to get through traffic to push it onto the shoulder. What I thought was about to be a case of a road rage fight turned into a case of "road polite".
