Only got as far as reading page 1.
I would notice them driving in the middle lane from a long distance back as I am an awesome driver, start flashing my lights at them furiously. Of course because they are a middle lane driver they wouldn’t even notice. So I would get right up there arse and keep flashing and start gesticulating at them. When that doesn’t work its pull in to lane 3, drive along side continuing to call them an anker.
When that doesn’t work (because they are still blindly looking ahead with no idea whats going on around them) I would give them a punishment pass, indicating to the left lane and then brake hard to again pull up along side them. Again they would still have no idea I was there. So I would then floor it in to the distance, at which point they would flash their headlights, as they begin to realise that they are not the only person on the road, and I was in fact behaving like a right c@ck.
That will teach them a lesson
