Have you tired submitting an issue? No one could map to a place I used to live out in the sticks accurately but I submitted a bug/issue to Google Maps and Apple and they fixed it.
No I haven't. Will totally do that in order to save time explaining to friends why they can't use Apple Maps for navigation to my house. I just assumed that submitting maps bugs is the same /dev/null form as normal bugs for Apple software, but it seems it's a separate process and they are actually responsive. Thanks!
FWIW, I have submitted Apple Maps corrections several times in the app, and have always received notifications that my map updates were completed within 1-2 weeks.
Ranging from simple updates like hours, address corrections - to more human-oriented updates like "The end destination point is about 500 ft off from the actual location".
I believe someone really is looking at them and correcting them.
