This seems to further highlight a need for a generic way to treat direction-sensitive information, in a way that can be processed by editors to automatically switch the left/right or whatever if a way is reversed. I know key namespaces are generally shouted down, but it would be a straightforward way to deal with this. i.e., left:bus_stop or left:house_number or left:my_heart_in_san_francisco. :-P If a way was reversed, the editors could change all the left: to right: Would need to apply to relations, too, though, and it starts to get tricky. But at a minimum, if a way is reversed, and it belongs to a relation containing direction-sensitive tags, the editors could prompt the user to confirm the action. Just brainstorming here, I welcome your thoughts. Karl
