I see both points--and I have 3 that have their dl and one ready any time (we need a reliable vehicle for her to practice--she has passed drivers ed)
Anyway, I was never taught directions--just go this way--turn right turn left etc--Have no clue East or West etc. If giving directions or receiving directions I need clues--such as on the corner of turn right--you will see a gas station etc.
My sons and my husband--don't need that--it was natural--they knew directions from get go--it was in bred---you could say I am on the east side of the street they knew where to go--if you told me you are on the east side of the street--I would say--so when I turn are you on the right or left--i would have no clue.
My dd also has her Fathers sense--she can tell east west etc.
Sometimes we all joke in the car--so what direction are we traveling--of course everyone but me--gets it correct! The only times I get it right is if I am on a familiar road--and I know heading into Chicago is East and going to the suburbs is West--but I have to be on the correct road for that to work--or my husband went to a school that had a direction in its' name and I would sometimes figure out--oh this road runs East and West--his high school is North so I must be going this way--but that is rare
SO GPS for me--that is a good thing--however--they can lead you the wrong way--and have many times!!! Especially if the map isn't updated!
My soon to be driver is similar to her Mom--doesn't have the best directional clues--though her Dad tries to teach her. She can get from place to place with jsut the same cues as I need.
I travel with people all the time--and they have great abilities---when they have me as a co driver they all know we need mapquest with exact directions
SO--yes--if you can teach them--GOOD THING--however, I think many just don't have that ability.
I wonder if any of it is math related--because I can do basic math--especially if it deals with coupons---but algebra etc--is not good---My ones that are good with directions and my husband--excel in math-----my dd that is like me--well as stated--just like me--
SO___GPS can be good as long as you know they can steer you wrong (once we were going to Chicago Bears Training Camp and it had us driving in corn fields but we were on the high way --of course dh was driving--it was me I would have been confused--and yes, we have updated the GPS since then--another time we were driving with people that are great at directions--and we had mapquest with us too---mapquest told us one way to go--the GPS different--the person followed the GPS_-which took us 30 minutes out of our way!)
So--map reading should be a part of drivers ed--and you should try and teach it--but if you are confused like me--then GPS can be your friend
