'wheelchair' is quite possibly a different situation. Is 'wheelchair=yes' the default assumption anywhere? For the access and transport mode tags, the routing engines take 'yes' as the default for a good many types of ways; 'highway=path' or 'highway=track' default to 'foot=yes'. Where I don't know for sure that foot traffic is lawful, I don't want to tag 'foot=no', (likewise, bicycle, ski, motor vehicle, etc.). And the default for the type of the way is 'yes', so I need a third value. That seems to be what 'unknown' is for. For that reason, there are some snowmobile routes that I've tagged 'highway=track access=unknown snowmobile=yes' in that I know they're lawful for snowmobilists (who pay a special tax for the privilege, assessed on the registration of their sleds) but don't know the policy for other modes. _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
