I have anecdata here. A single lane, paved but rough road, signed 'no entry for deliveries' regularly has delivery vehicles coming up it because their GPS navigator told them to. The sign is large. The track is almost half a mile long and has nowhere to turn around at the end. It is very difficult to get the navigation providers to remove this private access from the maps. Even if they do, there are many people who will never update their satnav software. This lack of updating may become an increasing problem as roads change and hardware ages, but directions remain the same.
