Buying a satnav for your car doesn't justify no longer being able to read a road atlas, just in case, if we are talking analogies.
But I know a youngster or two today that refuse to have a map in the car (for when their satnav gets them lost)
I can only conclude they don't want to show their ignorance to their girlfriends by holding it the wrong way up and takinga left turn when it should be right
