Are we not splitting hairs here? Certainly, the instruction to a learner driver is that the chopsticks sign indicates the start of motorway regulations, including any implied speed limit. Likewise, the standard signing practice is to place these signs at the commencement of any road that leads inescapably to the motorway. Our tagging practice is to reflect this "motorway zone" through use of the motorway or motorway_link tags. So far so good. If I'm reading you right, you're describing situations where the chopsticks sign appears some distance past the point of last escape. That happens from time to time, and is simply a case of the sign being wrongly placed. This is particularly common in Ireland, where there's huge variation in the placement of the sign, including some recent cases where the sign has been practically at the merge point with the mainline. My personal practice is to ignore the implication of badly placed signs and apply a motorway or motorway_link tag from the point of last escape. This provides the most useful view of the on-the-ground facts and should also reflect the underlying legislation for the road.
