If I choose to drive on anything except the freeway, I get told the road is closed, drive it anyway (the road is, after all, not closed) and spend the entire journey with a mapless screen. Great 4G+ reception the whole way. Happens all over NSW. Weird.
Different people will have different experiences in different locations.
In some locations Apple Maps is better, sometimes Google Maps is better, sometimes you have to resort to using Factory GPS (which is always terrible) and sometimes (Shock! Horror!) you have to navigate using road signs, your eyes and local knowledge.
That said, sometimes I wonder if an OSM navigation system would be much better. At least both Google and Apple allow you to provide feedback when something is wrong with their maps.
In newcastle I have generally found Google Maps innaccurate at best, adding massive legs to short trips at worst. Apple maps hasn’t sent me on doglegs yet in Newie.
Rurally, they’re both bad, but useable. But over the last year they have both got a lot worse.
I miss my NSW UBD paper book, frankly.
