This basically ruins the entire purpose of a traffic circle as a control mechanism.
The point of a traffic circle is that it's a wide open space. As such, you're required to approach slowly, yield right of way to occupied traffic, and proceed to your right SLOWLY until exiting. If you operate your vehicle with an eye towards not running into someone else, it just isn't that mentally taxing.
Now, everyone's going to want to read the lines. They're going to expect everyone to stay in their own line, while they fly through as fast as possible.
Frankly, if you're enthralled by gray bricks and $20 muffins, let someone else drive you.
