- I know that a particular ford openstreetmap.org/way/47302278… is impassable by cars and have tried to mark it as such however even after this change and allowing routing engines to update many still seem to use the route. (e.g. Osmand+) - Is there anything else I should have done or have I have done incorrectly that should be fixed?
There is an approved tag, 4wd_only, that fits very well. But as with all tags, it’s up to the engines to recognise and honor it.
A way to fine tune it would be using the acess restrictions. Maybe vehicle=no, ohv=yes? But I’m not sure whether routing engines are so vehicle aware.
