for route=road relations order doesn't matter much. It's impossible to

A meaningful criterion to sort a route is so that two adjacent ways of
it share one same end node.
In other words, that the route is ordered the way you travel it without
interruptions.
That's what the "sort" buttons of JOSM do.
And, beside finding a segment more easily, the schema of the route made
by JOSM shows the gaps (missing pieces).
And in particular it will show if the road is circular.
For example, if you sort the N30, you will see a gap between Boulevard
de Fraipont and Avenue de la Libération.
And 16 other gaps in total.
Last time I spoke of routes with a Potlatch user, he told me he couldn't
sort routes.
I don't know about ID and that's quite a time ago.
The N30 should be sorted and corrected.
I will let Nathan do it if he's busy with it.

Hello!
I was doing some editing on the N30 near Liège, when I noticed
that its
relation was completely unordered, with ways near the city center
being next
to ways much further south (see relation `124374`).
The wiki defines a relation as an *ordered list*, yet only
mentions order for
bus lines. Is there a need for the road relations to be ordered
correctly?
