I agree.... the traffic circles are a matter of driving in the proper lane and using the lanes properly.
Just as an experiment, I watched the webcam over Spanish Springs Square a few days ago. the camera was trained, such that I could see the corner and watch traffic travel around to the left. Keep in mind, this is a one-way street with 2 lanes of traffic. I watched for about 5 minutes and fully 90% of drivers started from the outside lane and cut across to the inside lane [around the corner] and then back to the outside lane. Not sure why there are lanes there??? No one seems to adhere to proper lane usage. Golf carts were the only exception to this experiment. Here's the website...check for yourself...if the camera is trained in the right place.
Cheers.....
