Roundabouts! Don't get me started in roundabouts.......
a) Those who pull up to a completely clear roundabout and then stop because their 'observation zone' doesn't exceed the end of their bonnet, b) Those than have no lane discipline and 'straighten' the roundabout c) Afrorementioned performance car drivers who scream up to a roundabout at 80mph, and then drive round it at 10 because they can't use a steering wheel.
