in the long run, we should consider whether there should
be tagging extensions to cover access routes that should be
routed, or perhaps a more nuanced approach to access roads
from routers.

i have a couple of recent cases where OSM based routing has
produced bad results because of these sorts of issues; some
require tagging extensions and others might be addressed
by adding specific criteria to routers as to when service roads
are permissible (e.g. ferry approaches or at route endpoints)
