A very long time ago I ran an analysis on the whole of Europe and found it to consist of (only) three large non-connected parts. However I looked at *any* way, not just what I considered to be roads. > [1] Ways with the "highway" attribute with following values: See http://tagwatch.openstreetmap.fr/france/en_stats_highway.htm for a list of things used. Try running your program and have it work on anything tagged highway=... - does that change things?
