Seattle proper has no proper/modern roundabouts.

It has hundreds of traffic calming circles which are often confused with roundabouts, but are not in the same class. Roundabouts have dividers at each entry/exit point which are lacking in neighborhood traffic calming circles.

Technically you can go any way around a traffic calming circle you want to, because they are too small to accommodate delivery trucks going counterclockwise. It is highly recommended to go counterclockwise if you can, but not legally required. They have no more legal significance than a speed bump.

This stuff boggles the mind. Make a way to get around that's easier, realize it's too easy and causing problems, so then hobble it ineffectively— thus creating frustration but also retaining the danger. All the while watching ads about 300 hp luxury work trucks and "sport" vehicles. What a bizarre slice of modern life.
