The car in the right hand lane will be cutting across the bow of the car in the left hand lane. You have to watch out for this. Both drivers are following the rules, but there could be an issue if the car in the left hand lane isn't paying attention.

This little diagram is nice, but it doesn't address cars entering at close to the same time from different points. It only shows two cars entering from 6:00.

If you are already in the roundabout, the person at 3:00 is supposed to yield to you, so there would be no problem
