I know we have to indicate to exit here in Queensland. For whatever reason many in my area do not do that.
Think about the phrase "Give way to any traffic already in the roundabout."
If that were taken literally, traffic would bank up to choking point real quick. No one I have ever seen follows
that rule. On busy roundabouts traffic from just one direction can be endless in peak hours. Roundabouts would be
unusable. It seems like a CYA rule put in to protect the judiciary. You hit a car that was in the roundabout, you are
in the wrong, no matter how big the roundabout is or how many lanes? Ridiculous . . . but maybe necessary.
I can't think of a way around it. Excuse the pun
