Regarding:
it doesn’t route across the intersection for any mode but walking/hiking, and in looking at the OSM data, I just can’t see why not. Any ideas why?
I looked at the edit history for the area, and seemed to get a flood of worldwide edits that have nothing to do with this area, so if there was a recent change that the routing engine just hasn’t picked up yet, I don’t know how to find it (so pointers there would be appreciated, if applicable).
Thanks.
