OpenStreetMap
I read about a navigator on the web that uses our OSM data called: "OpenStreetMap routing service": http://tile.openstreetmap.nl/~lambertus/routing-world/ and with that I checked a bikepath I made and it works! That gives me the first real clue that I'm doing this right.
On another check the drawn path stops on a connection between two roads that where already drawn in there by AND. I changed a little thing and I have to wait for wednesday to see what effect that had in order to deduct the problem. At first glance the two roads look identical tagwise, but I created another attached road to the same node. Maybe I messed something up there. We'll see.
I also again added a bunch of wood patches, small ponds and streams.

I think you will be able to verify the routability of your changes a little faster
My experience it that I can check my changes with one days delay by the following procedure:
Use wget http://download.geofabrik.de/osm/europe/denmark.osm.bz2 to get the proper data.
Use java -Xmx512M -jar "mkgmap-r630\mkgmap.jar" to create a proper IMG file
Use GPSMapEdit from http://www.geopainting.com/en/ to build and verify routing
First thing to do in GPSMapEdit is to build the Routing list with
"Tools->Genrate Routing Graph -> Using Coinciding Nodes of Polylines"
And finally the "Test Routing Graph".

You can alos check the routability of your work 'in the field' by using an application on your mobile phone. Have a look at http://www.we-travel.co.cc
Greetings & good luck, Sebastiaan

I'd heard about this but haven't tried it. Rather awsum!
Unfortunately it fails a bit on bicycle routing. Try 'network house, shrewsbury' to 'berwick avenue, shrewsbury' and you'll see what I mean...
Car routing seems accurate, though! Excellent work!

Sorry, meant hadn't tried it until now.

@Higgy, I had a look at your Shrewsbury bike ride and the way I see it is that: from the point you started there is no road that allows for bikes. Everything connects tot the A458 (highway=trunk) so the navigator is starting from the first road that allows for bikes and connects to your destination.

Higgy, you're right. I noticed now too that it doesn't perform 100%.
