I am truly amazed by the comments on this thread. How about a little dose of reality.
IT'S A CAR.
The main reason for not allowing a woman to drive your Porsche is pretty simple, male ego. Put your Johnson back in your pants and get a life. To think that a woman can't drive a Porsche only shows that you haven't been to enough ax or DE's. Granted, some of the women can't drive, but it shouldn't come as a surprise that neither can some of the men. Do you really think the woman who concours her 930 doesn't love her car as much as you love yours?
Forget all that crap that she'll sideswipe a fence post or crunch 2nd gear, so will your brother.
Some of you are emotionally attached to a machine. Sell it. Transfer some of that attachment to a chain saw or electric can opener as it would be a he11 of a lot cheaper and just as realistic.
Perhaps if there were a little more "of course you can drive my car" you wouldn't be spending so much time with the dumb one's.
