[OSRM-talk] Ferries dot gone?

Hey Jürgen,

I think you are hitting a change in behavior that occurred between the
4.9 and 5.0 versions. It is not possible to start on ferries anymore.
That means if a route over a ferry is not the fastest route, it will
not get taken. Combine that with the fact that most ferries don't have
a `duration` tag (hence defaulting to a speed of 5 km/h), you will
only see them used if there is absolutely no way.

However in the case above, I think you are hitting a different
problem: The island is not reachable because the paths on the ferry
are not accessible by cars:



I'm not sure if these ferries are generally accessible by car, but the
tagging would need to be fixed for that.
