Since nobody else replied, firstly the talk mailing list is probably
more appropriate for this, and maybe the talk-us list.

Do I understand you correctly that you have an existing map database
of some of the road network the United States and you plan to merge
the OSM dataset with that database to use in some product that you're
offering, and are wondering what the best way to contribute back would

If so the best way would probably be to aim for getting all your data
into OSM, and just adding extra tags / relations / ways / whatever to
express what you need out of the final dataset.

Yes please. Eventually we want the sort of detail your dataset
probably has, e.g. number of lanes, lane width, detailed information
describing intersections etc.
