Things cyclists should know … POV driver who's incapable of cycling

Re the tinted windows- It is safest to assume that every car or van I get stuck behind hasn't seen me, and might do something unpredictable. I always take the lane and hang back.

As far as this goes-

Please don't
madly gesticulate for me to pass you, your arm movements causing you to wiggle all over the road. If my initial assessment was that it's not safe to pass you, what you are doing is making passing you less safe.
pull over to the kerb and get off your bike until I have gone past. I'm not mad about the implication that I'm such a poor driver that I can't maintain a safe following distance behind you.

I have often slowed down and pulled over to let someone past- if it seems likely I will be holding them up for a while, it seems only polite, especially if I am creating a small tailback. It also makes sense to wave someone on as you do this, so they know what's happening. This often depends on how the driver behind is behaving- If they wait patiently, at a safe distance, I am more likely to go out of my way to let them past than if they tailgate and beep. I often let large vehicles past on hills, as they are harder to control at slow speeds, and their close proximity is intimidating.
