[talk-au] When does a road become a track?

[Mark Pulley]

This might sound like a silly question, but I was wondering if there  
is any guidance on when a road becomes a track. I've been driving on  
dirt roads since I first learnt to drive, so I might tag a way  
highway=unclassified surface=unsealed, where someone who has always  
lived in a capital city might see the same road and tag it  
highway=track tracktype=grade2. I'm particularly thinking of roads  
through forests (in particular of a road near Mt Canobolas, Orange  
NSW), some are in good enough condition to definitely call a proper  
road but others aren't as well maintained, narrower, more eroded. I  
haven't got any sample pictures (was busy driving!)

For those interested, the location I'm thinking of is here:  
http://www.openstreetmap.org/?lat=-33.3897&lon=148.994&zoom=13&layers=null  
(click on edit the show GPS traces - the GPS trace with no way  
currently present is where I'm thinking about the tagging).
