if you don't like roundabouts then don't go to swindon!! it's as simple as that really they seem to love them there for some awful reason...
so far as roundabouts go, I can understand why a lot of people from countries that just don't have them get a little scared by them, but there are some really simple rules, and provided that you follow them then you'll always be fine.
bascially, on the aproach to a roundabout there are usually two lanes, if you're turning left, you use the left hand lane on the apprach and signal left.
if you're going straight on, you use either the left or right hand lane on the approach, and don't signal,
if you're turning right, or comming all the way back around, you use the right hand lane on the approach and signal right.
when you get to the roundabout, if there is traffic to your left that traffic has right of way, (assuming that they can go, for instance, if there is a queue of traffic to your left, already giving way to someone comming off the roundabout where you are waiting to get on, then you just drive.
roundabouts are easy, I love 'em, there isn't anything scary at all about them, honestly they just seem to make really good sense to me!
must more sense than a light controlled intersection anyway!
