At the moment, you cannot do this. The upcoming API 0.5 includes some new features 'relations' that are supposed to help encode this sort of data. For now, just hold on to a list of these to go back to.

No, there is no tag to draw a nice cul-de-sac. Some people add a little loop to the end of the road to get a bump drawn. Personally, I just ignore them.

I generally do.

Good question. Options are

1. leave it unnamed
2. Pick one and name it that
3. Make the cross piece an xxx_link (to match the divided road) and leave it unnamed. Maplint/validator does not complain about unnamed _link roads.

Generally yes.

Also consider tagging larger through residential dual carriageways as highway=tertiary, abutters=redisential

Brent.
