Here's how I'd interpret a "highway=track" with no access tabs in
England or Wales (or at least the bits that I tend to frequent),
particularly with regard to foot access:
1) If it's got no other tags on it (e.g. no surface or tracktype tags),
then there's a risk been added from imagery alone, and I wouldn't assume
that I could route over it (especially not to "get me home before dark"
on a circular route).
2) If it's got any sort of other tags on it (surface, tracktype,
designation, width, mtb_scale) I'd assume that someone's been down
there, so access is at least "not physically prevented". I also find
background GPS layer that iD uses for this useful (though I doubt that
you could do much with that?). It doesn't mean that access is legal
though, so I wouldn't assume that I could use it.
3) If I was recommending to someone else whether or not to take a route
over a highway=track in England or Wales, I wouldn't suggest it unless
it had either explicit access tags (or a designation tag that suggests
that it ought to have an access tag).
