Hello,
when using the website to create a route from Livorno ferry port (43.553334,10.300656) to Brixen (46.719148,11.650824), it calculates a route from Livorno to Bastia (Korsika), then to Calvi (Korsika), then to Genua containing two ferries, although routing options are set to prevent using ferries!
When I set the route start a few kilometers away from the ferry port (43.558415,10.306571, away from the coast line to the inner land), everything is OK, then the route is only on land.
Is that a bug inside the openstreetmaps map?
