Using turn signals in the roundabouts is a ridiculous idea. What happens when the approaching car puts on his turn signal to exit then changes his mind at the last minute or the turn signal is on and the driver is unaware it is? This happens frequently at normal intersections and could cause a major collision in the roundabout. Better as it is to just obey car on the left has right of way. Easy to understand.
