My favorite "backseat driver" story involves two other couples, and my wife and me, going into NYC for an event. Everyone was giving driver their thoughts as to where we should go coming out of the Holland tunnel. Apparently, by that time he was fed up and literally stopped in the stream of traffic and turned around and looked at me and said "and CL, which way do you think we should go? I feel as if it's important to get everyone's input." I just laughed and said that I trusted his judgment. Meanwhile, horns are blaring all around us and he's ignoring him with a very calm demeanor, saying "and everyone else? Does anyone else have any further thoughts?" The car was dead silent at that point and finally, he pleasantly says "great thanks for your help everyone."
I thought it was hysterical.
