That would probably be mine. I loaded a single long gpx covering maybe
300 km along a motorway (Canberra to Sydney). JOSM let me load it as raw
data and upload the lot, but I couldn't get it to become a way. This was
a few months ago and I can't remember what the behaviour was, but I am
sure I assumed it was because of the relatively large number of segments
I was trying to make a way from.  I gave up and decided to collect more
data while the tools, tagging schema, and so on stabilise.
