Ugh, I hate roundabouts, they're so annoying. I don't think there should be any in the US. No one (including me) knows how to use them. I almost got hit by an Audi the other day when I was pulling into one. I thought that he would stop for me, but appearantly I was the one who was supposed to stop for him. They're just the dumbest things, I don't see why there can't just be a traffic light or a 4-way stop. Maybe for Europe they're useful (as there seem to be a lot over there, especially in the UK) but in the US they are just pointless and confusing.
