If it has only been observed with travel time messages and other informational messages, then how do you verify it won't be used for more in the 1% of cases, and does it actually matter? I'd be inclined to have all big matrix panels tagged traffic_sign=variable_message, with Variable Speed Limit Signs and Lane Use Signals different traffic sign types, maybe traffic_sign=variable_speed and traffic_sign=lane_control (I've not checked taginfo to see what people are already using) which would allow navigation apps to notify a driver about a variable speed limit zone (or does that belong on the highway?), however this is getting out of scope of Graeme's original question. -- Jono
