Dear Ben,
I've opened up a ticket: http://sumo.dlr.de/trac.wsgi/ticket/1878
I suppose it's a bug triggered by importing data across multiple UTM zones or
somethink along those lines.
You could help to pin it down by trying to create a small data set which
triggers the bug.
Somethink like taking the whole scotland area and filtering it with OSMOSIS
http://learnosm.org/en/osm-data/osmosis/ to only include motorways (The smaller
the better).
regards,
Jakob
