Nice!
Also, it did just occur to me that they might not even be using OSM for the *address* part of the car's maps. Addresses are basically non-existent in lots of areas in OSM, so this whole thing might be an issue with whatever additional address data source they might be using (combined with OSM's streets or whatever). If any.
I guess we'll find out! Haha. You'll know your truck got an update when you see that parking area shape!
