Not only for bicycles, also for cars without autobahn. Short routes (20km) works good. It seems the algorithm need a autobahn. Its maybe only possible to calculate the short way to and from the autobahn because long distance routing not right possible. When i start bicycle routing in my home town, and want drive in North direction, with bicycle (Ostsee) it let me drive 25 km soutwest direction...... and go then in north direction and use always the longest possible road. I dont know why it dont drive over rome. If you then use "Shortest Route" its also not the best route. Only the pedestrian mode give me a good bicycle route. see also: <a href="http://forum.mapfactor.com/discussion/comment/5655#Comment_5655" title="" TARGET="">Strange routing for bicycles</a>
