Are women bad drivers? I wouldn't really know, since I can't drive yet, but the overall statistics that insurance companies go by show that young men are the most likely to drive irresponsibly, not women. That's not to say that all young men are bad drivers, and it isn't to say that all women are excellent drivers, but the official stats show men as being worse, particularly if they are under 30.
Because our intelligence is so high we forget that driving is a necessity and that even us geniuses need to do it too. No. It depends on the person, age, background, education. Women just get a bad rep because a select few of them are bad drivers.
