Who's the more dangerous driver?

ScienceAGoGo had an article posted entitled Women Drivers Crash More Than Men which was kind of interesting. On one hand

As reported in the June issue of Epidemiology, American women were involved in 5.7 crashes per million miles driven. Men, on the other hand, clocked up just 5.1 crashes per million miles. Given the fact that men drive an estimated 74 per cent more miles per year than women, the figure is surprising indeed.

On the other hand men are three times as likely to die when they crash. Which is worse?

Some of the above statistics might also be accounted for by a higher percentage of professional drivers amongst men who, with more experience, seem less likely to crash while racking up a lot of mileage. Running up against the clock (i.e. potentially falling asleep) and driving larger vehicles might also account for higher-damage collisions.

Another thing to note is that there's also a fairly significant age dependency in these figures - teenage boys do indeed crash more than teenage girls, but older women crash more often than older men.
