3. The sharrow designs I've seen dictate a fairly specific lateral position. I think the design could be changed to not be as specific, for example just a wide lane spanning bicycle icon, or an icon that shows multiple (left, center, right) positions. At intersections approaches on roads with one same direction lane the left position could have a left turn arrow, the center a thru and the right position a right turn arrow. Just a rough idea.
I think you've got something with your observation that the absence of a sharrow or a bike lane could signal that bikes shouldn't be there. + a bike lane says that's the only place a bike should be, doesn't it? What's wrong with just riding in the road? "I doan need no stinkin' bike lane."
