Route to Mount Washington (New Hampshire) won't work.

So, while exploring potential trips,I asked for a Route to the top of Mt. Washington. It routed me up the cog railway! There is no drivable road on the west side of the mountain, just a very rough service track along the railway which isn’t open to the public. The auto road comes in from the east side (the white line), and is the only way a car can get up there.

Thinking it might be a bug in OSM, I went there, but no, this “road” is correctly labeled with type “track” which should no be used for car routing.
