Is it possible to encode arbitrary maxspeed values or can we only set in steps of 10km/h? For example having road road_speed=7 associated with 35km/h, road road_speed=6 with 27, road_speed=5 with 23, road_speed=4 with 20, road_speed=3 with 17, road_speed=2 with 10 and road_speed=1 with 5km/h. The difference this should make would be enough to only set road_class=2, 1 and 0 and avoid the big time penalties for sharp turns that happen in road_class 4 and 3. This would be great for bicycle maps. In Mapsource one can change the speed oneself, I noticed that dividing default speeds by a factor of 3.5 produces pretty good estimation of arrival times for bicylces (when using the car/motorcycle setting, as bicycle produces rubbish routes) but on the GPS this is not possible. @Thilo, do you understand the code good enough to write a patch for this if possible.? I have problems understanding in which files the maxspeed is handled. Cheers, Felix
