I live at the end of a cul-de-sac and the main road runs next to my house. However you cannot access my house from the main road. The roads do not connect and there is a wall and fence. That doesn't stop every GPS and delivery app from telling people you can get to my house from there. I can't tell you how many food delivery drivers who never read my directions about turning into the neighborhood. A few have been so dense that I've had to go climb the fence and meet them at the main road because they just couldn't figure it out.
I remember years ago I went to a concert with a friend, we used Google Maps to get back home. It told us to drive straight through a cul-de-sac. I am sure the home owners wouldn't have appreciated it.
This happened to me at my old apartment randomly. After giving the correct directions for month, one day Google decided “no, you have to go to this OTHER road and walk through the alley!”
But of course, there was no alley.
That being said, I put in the request with Google Maps to fix it and it was fixed in about 3 weeks. Took 2 weeks to even figure out why all my deliveries were being delivered a street over, though.
