The logical step from this is to make streets relations 
themselves of all of these little sections. This would 
also be useful for bridges (i.e. a road could be 
continuous with only a section being a bridge) and all of 
those non linear residential streets. It might make the 
rendering quite a bit clearer too. A route could have a 
reference the same and change its name several times 
(major routes through cities quite often do this).

Now of course this seems to be taking us back to segments 
and ways, but at least this time the segments could have 
multiple nodes.
