Yes, it's certainly quite expressive, at the cost of complexity - and having to use relations. One of the advantages of simply setting a "divider=" tag is its simplicity and succinctness. One tag, and you've got something that will render nicely, and be useful for routing. I see four essential tag values: divider=none (can freely cross) divider=marked or something (do not route a car across this, but a pedestrian could cross it) divider=median_strip (again, do not route a car across this, but you could drive across it in an emergency) divider=barrier (a physical barrier that would probably stop a pedestrian) Not certain about the key or tag names. Maybe: divided=no divided=line divided=median divided=barrier Does that work? median=? I guess we also have to be careful about the word "barrier". Setting a highway to be barrier=yes would normally mean the highway itself is somehow impassable to people not on it...but wouldn't say anything about u-turns.
