I don't need to. It is allowed to, based on the signalisation I see on Mapillary. You still didn't answer my question how an only straight on sign mysteriously should become a no left turn. You aren't helping the discussion. YOU are the one who did the edit, it's YOUR responsibility to be able to explain your reasoning behind it, so the community can understand. I can't, that's why I'm asking, and I'm expecting an answer based on facts, not some mysterious mix of existing data, car-centric "logic" and assumptions. Thanks.
