Scientific studies indicate that lack of the male hormone testosterone is the cause of females' lower skills in driving and parking cars.

Apparently testosterone helps with spatial tests that allow men to perform better with three dimensional thinking than women.

It turns out most women have index fingers that are the same length as their ring fingers, unlike men, who have a distinguishable length difference between the fingers. Women who have ring fingers that are actually longer than their index fingers (in other words, those females with more 'masculine fingers' are much better than their female peers at these spatial tests.

All I know is that I used to ride to work with a girl who could parallel park at 60 miles an hour while I was holding on to everything I could in blind terror.

Is the best driver you know male or female? The worst?
