I've dozed off once at 50kph... woke up as the wheels scrubbed along the kerb. Trust me... this is something you don't forget. So I don't think there's actually much point in reporting the guy to the cops -- he's almost certainly learnt his lesson and won't do it again.

That's what I was thinking too.

But the problem is recognizing that you are getting drowsy early enough. If you fall into the trap of "It's only another half hour... I can manage that" when in fact you can't, then ten minutes later you probably won't be able to make that decision. Much more sensible is to pre-plan your drive while you're wide awake and thinking, with rest stops as recommended by the AA and NZTA.

I've only felt I needed to stop because I was too tired once. It was heading from Auckland to Hamilton, which is just over an hour's drive for those who don't know it, late at night back in 1998. So I stopped in the road works gravel storage lay-by just out of Ohinewai, which isn't quite half way, and was out like a light almost immediately only to be woken by the cops half an hour later asking why I was stopped there. I got a little bit short with them and said "What the @#$% did it look like I was doing before you woke me up? I felt tired so I stopped for a rest." I guess I could have been a drunk, but still - I'd have been a semi-responsible drunk!.
