If I am waiting to turn right on this roundabout (because there is already a car in the roundabout and one following close behind): and there's also a car stopped straight ahead waiting for the cars, who goes first? Me or the other car? The reason I ask is, 80% of the time this happens, the car straight ahead of me doesn't move off the mark and sometimes the driver waves me through. This is causing me to have a bit of confusion. I thought this scenario would be treated like a normal right turn off of the main road? Wait for straight through traffic to clear before proceeding?
