Rule #1: Don't tell a woman that she can't drive, or that women in general are bad drivers.
They aren't! Plenty of men are terrible drivers, and plenty of women are terrible drivers. If most of the women in your life are bad drivers, you just have a really bad example to deal with, and it doesn't necessarily carry over to the rest of humanity.
Or maybe the women in your life are idiots! Who knows? If you're the type to generalize about women being bad drivers, it wouldn't be such a shock to find out that you associate with complete morons.
