My apologies. I didn't explain correctly. In my case, the person exiting the circle from the inside lane is exiting into a single exit lane. The signage when entering the circle forbids this. You must change lanes to the right/outer lane before exiting certain exits.
So my situation, 2 cars are traveling in the circle, one in the inner lane, one outer. Both want to take the next exit, that's a single lane. Inner car veers across outer lane to the exit, nearly hitting the other car.
