The Sharrows in are town are decent in a few situations. Mostly on roads which are designed primarily as bike corridors with very light car traffic. They work only because they advertise which streets are good for biking on and that's it. They communicate pretty effectively that if you are on a bike this is the road you should be on. In places where car traffic is moderate or heavy. I live in one of the top 5 most bike friendly cities in the US though and the transportation department does a pretty good job making good bike routes. As the survey suggests, the idea situation is where bikes have physical separation from cars by a long margin.
