andymoosemansm2n: Good point & you're right. I was trying to also make the point about how so many people don't understand how to use roundabouts, or the road generally & how that causes other issues & delays :)
sm2nSurely the roundabout standoff (yes, I've been there) happens precisely because the participants do understand and obey the rules of the road. Or is there some rule I don't know about that actually dictates who should make the first move?
