turn:lanes illegally ignored

There is an intersection with the painted legal turn restrictions of turn:lanes=through|through|right|right;reverse. However, everyone ignores this and treats it like turn:lanes=through|through|through|right;reverse (note: this includes going over painted hatched markings). This would not be an issue except the traffic light's right turn signal is sequenced after the straight, so coming to a stop in the middle right turn lane (red light) would stop everyone going straight illegally (as they usually do) and could be dangerous (opinion).

Is there anything I should map besides the legal restrictions?

One Answer:

I would map the legal restrictions. My thoughts are that the turn:lanes and turn restriction relations in OSM will be used by navigation apps and those apps are most useful for people unfamiliar with an area. Giving people unfamiliar with an area illegal advice is probably not a good idea. Giving them legally correct instructions, even if the locals ignore the laws, should do no harm.

agreed. the "should do no harm" part is what I am most concerned about. If someone is new to the area they should be encouraged by the renderer to use the right most lane for turning right. I doubt renderers consider anything beyond turn:lanes for this though.
