If you're cycling and you know a car is behind you and wants to overtake, should you let them / facilitate the overtake or deliberately refuse and shout 'wait' at the car? When the road ahead is straight and clear for well over half a mile, when the car has been patiently waiting for a safe, straight stretch, there is no other traffic but the road is just that little bit too narrow for the car to want to do it without some kind of affirmation from the cyclist, ie stop pedaling for a few seconds and move a bit closer into the side of the road?
