If a path is a "Via Ferrata" (highway=via_ferrata) the auto rute doesn't work
Thanks for the feedback. We'd need to add a new extra setting for this as most people wouldn't want to be routed on a via ferrata. We've added it to our feature requests list (number 125) where anyone interested in this can vote for it.
Ok.
choose if go on "via ferrata" or not when make a route is also better
