On a fairly open roundabout I can see a car approaching from a road on the right. Given that I will be on the roundabout first who has the right of way? Is the rule give way to traffic on the roundabout or give way to traffic on the right?
I see so many cases where because the driver entering the roundabout sees there is no traffic on his right he assumes he has right of way.

In Australia the rule is clear, you should give way to traffic already
in the roundabout, I would imagine that your rules are similar,there is
no give way to the right, give way means that if there is a danger of
them hitting you or have to brake you should give way, it does not mean
you have to wait for an empty round about
In your case you would have the right but would be silly to force the
issue resulting in an accident even though they would be in the wrong
