|Right about here, a glance back over the left shoulder, then aim for between triangles 3 and 4|
This traffic circle with a yield sign on a not-very-busy street always seems to work for me on my bicycle. I typically hit it about the same time as 1 to 3 cars, and we just flow through it. Except for the rare super-polite person who waves me through, an invitation that I am hesitant to accept, this just works.
When no cars are here, or bikes, I fly through. Or go slow through when I am riding slow. Zoom.
I like the good visibility here, too. Everyone seems to see everyone else. I'm still convinced in the power of the over-the-shoulder glance in this situation, by the way. If I hear a car coming with insufficient engine slowing, I give them the Glance, and they always slow down. I've also tried variations on the slow down/stopping arm signal, either the hand facing backwards pushing you signal, or the hand pointing down at the spot I am merge-stopping to. Those both seem to work pretty well, too. Although, honestly, it's most fun to just ride right through the circle when no one else is around.
