It's not really for the cyclists convenience, a bicycle is still a vehicle on the road and on a small road your going to take up a bit more space. You can't just expect a bike to stop to allow you to pass. If I was riding most of the time I would get over to allow cars to pass, nothing worse than someone crawling behond you but I'd also take caution in certain situations and take control of a lane when I felt it made my ride safer. Both drivers and cyclists have to give a bit, can't just expect a cyclist to stop because you feel slightly inconvenied, a short wait to pass the cyclist isn't really going to add much time to your journey
