Seems that app internal routing doesn't honor parking and private roads penalties.
If I use Live Map or Waze routing server -- they both plan a route around the private road. But when I have no internet connection (i.e. airplane mode), my app navigates me through this private road.
I have the same issue with Parking Lot roads. Could anyone please confirm this? If it's a bug, how to I report it?
It was here and all around the city center. Sorry, I had to restrict all the turns, so you can't try it now.
But as I wrote, I have the same issue with parking lot roads. So here is the permalink.
I'm also attaching the screenshot for your convenience.
