The paintings on the ground are abysmally useless from a safety standpoint, but at least SF in particular has bike markings that helped me find flatter roads and other cyclists to clump up with.

That being said, the one way sharrows can be less deadly is to make them borderline useless for other cars, such as Silver Street in Albuquerque. Silver street has medians in its major cross streets so that cars can't continue straight, but bikes can. This, along with the facts that its speed limit is 18 mph and it parallels larger streets the reasons it's not used much by cars, despite not having the excessive stop signs that most gridded neighborhood streets possess.
