My wife cannot back up our car into a parking spot.

She cannot create a visual map of her surroundings in her head the way most men can.

It doesn't speak of over all intelligence. She can do math problems atleast on paper as good as me.

Its why she doesn't like playing 3d games .

Its why most women dont enjoy 3d games but most men do.

If a woman does enjoy shooter games it's a good indication she is a good driver and can back the car up easily.
