Sharrow markings are typically (and properly) only found on bicycle routes that do not have dedicated bicycle lanes, and bicycle boulevards. cycleway=shared_lane in the US, save for locales that Did Not Get the Memo™, should also have bicycle=designated and be a member of the appropriate type=route, route=bicycle relation.
