I think one of the hardest parts of OSM is that the world is very
heterogeneous. You see that in the discussions about cyclepaths, you that in
software that using doesn't quite do what is locally expected (or needed),
and of course the quality of the data varies wildly.

So, I can only speak for what I see here in .nl. And that is quite good.
Whether is is yournavigation (based on gosmore), andnav2, or a Garmin gps,
I can expect to get where I want to be, both by car and by bike, and with a
reasonable route.

Of course, 'we' got lucky, and got most of the road network from AND, but that
doesn't include cycle paths, and it is not often that I come across one that
is missing.

But the main point is that from a tagging point of view, all of this is not
very hard. There are not that many tags you really need for a road network,
there are validators to help you clean up intersections, but the main thing
is to get out there and try to navigate using OSM data.

I think it is pity that nav4all doesn't want to OSM because you do need the
eyeballs get it right. 

In my experience, OSM data worthless until you use it for something. If all
you do is make pretty maps, you will never get what you need for navigation,
because you won't spot the bugs.

So, if we want to 'sell' OSM as suitable for navigation, then 'we' have to go
out and use it for that purpose,
