GraphHopper will now route cars over fords recorded in OSM, as confirmed here.
I was aware of this when the change was made because I’ve been keeping track of the GraphHopper driving distance from N’Djamena to Mongo, a route that is something like this:
The sudden rise in distance was caused by a mapper adding a ford between the two places; the drop is when GraphHopper started to route across it.
More details on the recording of routes to follow; for now I just wanted to show this practical usage example.
