Yes & no. The UK classification system is mainly based on route importance, with motorways bolted on as having specific physical characteristics (and also generally being the most important). I could well imagine a system where the classification is mostly based on physical attributes, and where it would be useful to put this in a separate tag, and let "highway" be used for importance (because that generally makes for better-looking maps). Perhaps local_highway=whatever-they-call-this-type-of-road-locally. Richard
