It's a nightmare we're probably going to have to address at some point if we want to do good routing. There are many traffic rules that are local, affect routing, and are not explicitly signed on the roads. Here's an example. In Queensland (and I think the rest of Australia) it is illegal to do a U-turn at traffic lights unless there is a sign that specifically says you can. It is legal to U-turn at road junctions without traffic lights unless there is a sign that says you can't. If you want a routing application to take this into account, we're going to either have a local rule that says "Don't U-turn at lights etc" or get every intersection with lights mapped with U-turn restrictions in every direction that aren't signed in the real world (good luck with that).
