could you elaborate on that? What in particular are non-contiguous ways? 
(Apparently you can put roundabouts in between, and they are still 
contiguous). Why are they bad? ...
If a road splits, but gets together again, should it still be together? ...
If there's already a Wiki-page on this subject don't hesitate to send me 
there. I've already browsed the OSM-site, but I'm pretty sure I missed 
interesting parts.

I consider this to be a hack, but if that's how it's supposed to work I'll do 
as told.
I think however, that contiguous ways should not be split (and state this as a 
rule). As already mentioned: our local motorway is split in the middle, and 
it is IMHO not realistic to ask people to get the whole motorway from the OSM 
site before annotating it (how else would I know if the motorway is 
interrupted).
