Can you explain why that roundabout wouldn't have a B37, given it's
actually part of the B37 route? If you leave out the B37 then you're
leaving a gap in the B37 ref's, surely that is inconsistent?

Are you sure you're talking about the right relation? Since I created
the M1 in relation in the last few days, and just checked it I can see
I messed up and actually added a point by mistake (now fixed) but the
ramps are part of the Princes Highway and South-East Freeway street
relations (since they are parts of those 'streets').

Is this yet another crazy OSM inconsistency? Surely any of those closed
loops are implicitly areas? In fact I notice mappaint in josm tends to
render closed versions of these as areas without any redundant area=yes
tag, so I'm not alone in my thinking here.

Perhaps a twig to the map features page with respect to this is need, I
find the reading of it very unclear and had been assuming from how it's
written that highway=traffic_signals is used for all traffic signals
(since they all controll traffic)...
