text: I doubt that it's OpenStreetMap that's sending them down there, as https://www.openstreetmap.org/way/315224879 has been only a footpath for 5 years.  See also https://www.openstreetmap.org/directions?engine=fossgis_osrm_car&route=54.2298%2C-0.6223%3B54.2298%2C-0.6102 .  There's always room for improving the mapping, but unfortunately I don't think it'll stop drivers going down here.
