I think a distinction needs to be made between:
1- Sticking to the speed limit and finding someone getting angry, coming up close behind, then aggressively overtaking
and
2- Sticking to the speed limit and noticing someone trying to overtake, then taking some action which prevents this or deliberately makes it difficult for them
I don't believe anyone is trying to argue there's a problem in sticking to the limit even if it 'angers' other drivers (EEN nutjobs aside) but I'm broadly in agreement with WC in that it's probably not a good idea to set about antagonising someone who has already marked themselves out as impatient and dangerous. I imagine this is going to be taken as me saying I think we should all roll over and let the angry people have free reign but that's not it. If I'm at the speed limit and someone is getting annoyed at that I'm going to ignore them and let them stew in it. But equally I'm not going to go out my way to make them slow down, or prevent them overtaking, that's too confrontational for me.
I do recall there's some bit of the highway code that deals with this, if I remember right (which I may not) it states if someone is trying for a dangerous overtake you should let them, because the decision is theirs to take the risk and not yours to try and prevent it.
