that's like saying after using computers and keyboard... no one knows how to hand write anymore...

as with everything in life... you do things in progression and with analytical thinking... it doesn't mean that you are thought how to use a pen knife and later given a chainsaw and you can treat it as you will a pen knife...

logical thinking cannot be taught.. it has to be self learned..

we might as well just teach newbies how to maneuver an 18 wheeler as well if that is a valid argument because there are many parking heroes in our community of drivers as well.. if they can't maneuver a decent sized common car in our country into a parking spot... they might as well learn to maneuver an 18 wheeler around so parking those small cars will become 2nd nature to them...
