Paul, thanks for replying to my examples:

This one's easy - you shouldn't have been there. It's only very occasionally necessary to accept a "three abreast" situation on a motorway. Usually a minor variation in speed will give you a gap to the left or the right. These gaps are your safety space and should be managed constantly.
The outer lane is nose-to tail travelling in excess of the speed limit. So, unless you break the limit, you have no option but not to overtake or accept "three abreast". Of course, the safest thing to do is hold back until a gap of more than two car-lengths draws alongside in the outer lane, accelerate and pass the HGV with that gap to your right. But then along comes PC Gatso...
Holding back isn't a safe option because you'll end up slowed down to 50 to let every tailgating HGV past and being the slowest vehicle on a motorway puts you in a higher probability of collision than does overtaking in "three abreast configuration".

The second one is harder, but there is a key element that you failed to control, and that's the tailgater. Assuming that the tailgater has not just arrived you should have got rid of him earler. Assuming again that you have done so, we have now respoved the incident into the loony overtaker - now trying to just overtake you - and the oncoming car. See this page on tailgating:
Thanks for your comments and advice. Strangely, the tailgater was the reason I was at the head of the queue. I'd slowed down a few mph to put a gap between me and the vehicle I was following and I was hoping the tailgater would either drop back or overtake. Unfortunately, it was the nutter two cars behind him that made the move

I suspect that when the nutter started overtaking, the two overtakees closed the gaps to try to stop the "queue jumper" from passing them, thereby exacerbating an already dangerous situation. Had they not done that, the Rover may have been able to get in safely.
Whatever, my anti-tailgating measure may have been a contributory factor because I suspect that the Rover wouldn't have tried to overtake had I been travelling a few mph quicker and two seconds behind the vehicle in front. That said, I feel that you've got to drive on balance of probability and by dropping back a couple of seconds, I reduced the chances of an accident from forseeable hazards. It took poor driving from (probably) four other road users to cause the situation.
