Just to be very precise about this, you must give way to any car which is already on the roundabout.
As I approach a roundabout of 4 junctions, I tend to look to my right. If there is nothing coming, I drive straight onto the roundabout. But this is not correct. As I approach the roundabout, if there is a car on the roundabout at the next junction to my left, I must slow down and let him go ahead.
And I think that this is where the confusion arises. If he nips onto the roundabout ahead of me, he is in the wrong. But if I rear-end him, I will lose the case.
But think about the poor cyclists. Cars regularly overtake cyclists on the approach to roundabouts, so I cycle in the middle of the road as I approach, so that they can't do it. Cars approaching from one of the other junctions, just ignore the bike anyway.
