What I believe you saw in the film was what I call gamer mentality. The target was assigned by an unknown person to a pilot who engaged the "Target". Then the call went out to get all of them.
It is my opinion that this will be how they handle it if you or I are the men on the street. The driver probably never thought. He just saw friends and possibly family in need and stopped.
Bad decision, but I don't know if you or I may not have done the same. This movie makes the MiLia event in RVN look like a fist fight.
