I've had to slam on my brakes because someone wasn't stopping (and then they waved at me to thank me for stopping for them...). But that was once after the hundreds of time through there. I know it's not quite fair since they're at different places, but compare the roundabout to something like 3rd and F at 12:30. It's a nightmare there, whereas even when there's a bus letting off 60 people walking to the apartments by that roundabout, it's not that unpleasant.
