We don't need a sense of direction or a back seat driver nearly as much these days since we all have GPS now. In the old days, GPS was a paper map bought at the corner gas station or torn from a phone book and the back seat driver was responsible for holding the map and saying things like, "You just missed our exit!" or, "I see the problem now--had the map upside down."
A backseat driver and paper map would have come in handy several years ago when I left a meeting and used GPS to navigate to my next meeting. I drove for miles blindly following the GPS directions, finally arriving 20 minutes later at my destination: the building right next door to the one I just left!
