After popular request I will now try to publish new maps on Thursday night (well next week lets see). For this update the main change is that avoid toll is only blocking very difficult ways. Avoid Unpaved roads, avoids unpaved (but not very difficult) ways. So you can use both or only one… Also taxi and emergency are changed around (next map update will make use of avoid carpool lanes, therefore I had to change them around). Full explication is on http://openmtbmap.org/about/autorouting/ .
Also avoid ferries does work now (and will avoid ferrys and cablecars/gondolas/mixed lifts).
