Sorry, I should have said something. I don't think that, by default,
"destination" should bar access to a route because the route may
become unusable for everyone. Bad news if you are trying to route to your
home in that area.

So as an alternative, if you do want to stop routing through ways that
are designated "destination", how about adding something like this to
your lines style file?

access=destination { set access=no }
hgv=destination { set hgv=no }
motorcar=destination { set motorcar=no }
motorcycle=destination { set motorcycle=no }
psv=destination { set psv=no }

Looking at the comments in RoadDef.java, it's not obvious what those
bits do.

It didn't apply to the current trunk, anyway.
