Indeed, legal restrictions often say a lot (maybe more than physical attributes) about the purpose/function of a way, from motorways all the way down to sidewalks. Just like physical attributes, it is an imperfect indicator when things aren't as expected, such as when a major highway briefly narrows because there was not money left to build it (a common thing in developing countries), or when a rural highway continues into a city, changing physical attributes because that small part of it was built by the city (with its own parameters) and not the country's government. > The real world is messy.

I've found that the difficult/controversial situations in OSM are much simpler to decide when thinking about a way's main function in its local context. So I see value in both a strict set of rules that solve 95% (hopefully 99%) of the problem of highway classification, but the remaining few % may require discussion and consensus by locals. -- Fernando Trebien _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
