For motorways and POIs, sure, but for everything else, it's a real crapshoot. It doesn't help that we have some agitating forces mass-replacing tags on the basis of The World According To Him, but that appears to be a situation of subtle mass vandalism that OSM is happy to ignore and highly resistant to actually confronting¹. >> Also provides consistency for routers, since >> I can pretty much guarantee there's not a router out there that >> arbitrarily changes it's behavior based on what part of OpenStreetMap >> it's looking at... > > Then you can pretty much guarantee that there's not a router out there > that works very well on OSM data across multiple locations. Yeah, that's something of an issue. We shouldn't make it harder for data consumers to consume the data just because the human factor is resistant to consistency. ¹ so whatever on that...it's a dead horse at this point, as much as I'd like mass vandalism to be dealt with, it appears we're unwilling or unable to actually handle such a situation.
