Top tip for motorists. A cyclist is on a narrow road, he's in front of you. Its a two way road, and the cyclist has decided to be right in the middle of the lane; where he is now, you physically can't overtake him because of oncoming traffic. Which is a problem. Now, if the cyclist were to move over into the gutter you could get past, although it would be a squeeze. What you need to know in this situation is that the cyclist knows that you're there. He's no more likely to move over and let you pass if you honk at him, you're not alerting him to your presence. In fact, he'll take your act as needless aggression, you're asking him to move over to a place where it isn't safe for you to pass him. So all you have done is you've informed the cyclist that he can't trust you, you've told him you're really rather impatient. What'll happen now is the cyclist will hold his position all the way along the road, until he's absolutely sure he can get to a safe place to allow the overtaking with no possible risk of you making a dash to get past him. Oh, and if you think that making feints on to the other side of the road into the traffic is going to help, you're way out there too.
