access=destination is IMHO a bad example for this. Penalizing those
edges heavily will cause OSRM to very hard try to use the next
possibility to leave the access=destination segments or to enter
them at the very last possibility. The cost for using
access=destination roads is not proportional to the amount of distance
you travel on that road, but its a one time cost entering the
road/segment/area.

In the end most of the time access=destination based roads build a
subgraph e.g. multiple interconnected roads and the area itself
is access=destination.
