I'm going to start putting unconnected nodes in with the tag 'questionmark' 
and the value being a string describing what I think exists there.

Suburbia is easily cut up into sectors divided by the more major roads. If I 
remember to concentrate on particular sectors one at a time it's usually not 
a problem. Cul-de-sac suburbia can usually be done sector by sector, going 
anticlockwise around the perimeter (easy left turns into cul-de-sacs) until 
you get back to your starting point. It's quite difficult to confuse which 
sector you're in, because you have to cross a main road to leave it. 

And naturally cul-de-sacs themselves are easy, because you can just traverse 
them recursively with a left turn rule.

I do this too - pronunciations leading to ambiguous spellings. I haven't come 
up with a solution yet. I'm going too fast to spell them all. I'd be 
interested if anyone has any ideas (other than taking photos).
