The new-ish rules for overtaking bikes

[YMFB]

You should not be waving them past, pull over if you like, make it easy for them to overtake, but let them make their own decision.

Following distance, two second rule.

My experience of looking over my shoulder is that previously patient drivers interpret it as an invitation to overtake immediately, regardless of whether it's appropriate.

I appreciate that's your perception. My take is that every driver behind seeing me look round at least knows that I know they're there. I rely on them to judge their overtake when the road allows to do so safely.

I do use the head-turn to indicate that I know they're there and also as a subtle indication that they can pass at their own discretion.

Me too.
