Ok, so I've just decided to look up this and see what I could find.
I found this Finnish study which says the following:
The main finding regarding risk factors and risk groups is that during the summer months, especially in the afternoon, the risk of falling asleep while driving is increased. Furthermore, the results indicate that those with a higher risk of falling asleep while driving are men in general, but especially young male drivers including military conscripts and the elderly during the afternoon hours and the summer in particular; professional drivers breaking the rules about duty and rest hours; and drivers with a tendency to fall asleep easily.

Now, it's one study.
I'd be dead interested to know more about the UK stats from that. And how the measurements of tiredness are comparing to the UK accident rate.
I am curious to know how highly women are scoring as tired compared to men. And whether this directly correlates to rates of accidents.
Cos we know women do have different levels of stamina to men. .
The Finnish study above definitely shows that men are more likely to have fatigue related accidents.
I think I would like to investigate and crack down on the why before looking to roll out more prosecutions for driving whilst tired.
As I say I think women are probably more likely to get the shitty end of the stick on this otherwise.
