I was on a roundabout when a police car, siren and lights going, came along. The roundabout is wide enough for two cars side by side, but the exits are single-lane traffic with an arrow to tell you to move over from the right lane almost immediately. So, I pulled to the left side of the roundabout against the kerb and braked so the police car could get past without me being in the way. The bloke behind me honked and shook his head at me - I assume for braking or stopping on the roundabout?
It seemed like the practical thing to do but clearly he'd have kept going and expected the police car to move around him. I think he was a wanker, but what do you do in this situation? Would you always stop and pull in to the side or would you sometimes just keep going and try to get out of the way of a junction?
