Understood absolutely.

But put that out of your mind. No matter how I or anyone else phrase it, 
no matter whether it's accompanied by a helpful smile or a superior 
sneer, you do genuinely need to sort this shit out anyway. You do need 
to make sure that your data is as consistently attributed as Google's 
(or OSM's UK data), because otherwise people, like Mr 41latitude, will 
compare the two to your detriment.

And you need to do that for yourselves. With the awareness of being part 
of an international project, sure, but it needs to come from US mappers. 
I mean, I personally dislike the overuse of relations to model 
absolutely everything, but you should take no bloody notice of me 
whatsoever and use route relations for your roads if you think it works 
well and will be reasonably in keeping with the rest of OSM.

So if, say, you think you need eight levels of importance within your 
highway network, yet OSM only has seven (motorway, trunk, primary, 
secondary, tertiary, unclassified, residential), screw it. Invent 
another one. Quaternary or minor or something. The Germans have done 
that (motorroad=yes) and no-one has died as a result.

Funnily enough only US people do that. :) Personally I'm more used to UK 
cyclists comparing OSM and Google. Google has no cycle paths or routes. 
The cyclists love OSM!

I think, actually, you have an advantage in that the US community is 
quite small: it's easier to get agreement. Whereas over here, where the 
community is big and fractious, it takes forever to get anything done. 
You're still young. Use the advantage while you can.
