I'm working out of a different office now and have returned to commuting by bus and train. On the express bus ride home, I opened up Apple Maps and set a route home just to watch how Maps behaves on the phone.
What I saw was interesting. Maps on the phone is basically identical to pre-iOS 13 Maps as far as visual behaviors. It's only on CarPlay that iOS 13+ Maps behaves differently. Which leads me to believe, for this reason and the myriad of glitches and problems we had with CarPlay during the earlier days of iOS 13, that CarPlay on iOS 13+ is a fundamentally broken experience compared to the "pure" Maps experience on the phone.
Again, I have spent the past few years navigating with Maps exclusively through CarPlay. Prior to iOS 13, the CarPlay navigating experience was basically identical to the phone in the following respects:
-3D buildings would appear at the same zoom levels.
-While navigating, Maps would consistently show you the names of the next four roads intersecting with the road you're on. As you pass a road, the next road ahead would be added in a smooth and consistent manner.
-The names of subway stations would appear as you get near them.
Now, on CarPlay ever since the update to iOS 13:
-3D buildings disappear when zooming out much faster than on the phone.
-While navigating, Maps still attempts to show the names of the next four roads, but doesn't show them in order. You might see the next two roads, then it skips one, and then the fourth is maybe ten blocks away. I thought that maybe this was Apple's new way of doing things, but after watching the navigation on my phone today, I think it's just a CarPlay issue. On highways, sometimes you might "exhaust" the next four roads, passing all four of them, and then not see any upcoming road crossings for a little bit. Then suddenly, the next three or four will pop in suddenly, despite those roads having already been on screen.
-The names of subway stations no longer appear as you pass them. You only see the symbol that a station is there.
This follows these additional CarPlay issues that appeared with iOS 13, and never went away:
-Navigation audio randomly being way too low, and having to reboot my car's head unit to fix.
-Not being able to access "My Places" in the destinations menu. It just won't be there. I have to enter the destinations menu, exit the menu, and then go back in.
-When starting a route, the camera is sometimes very choppy as it settles behind my car, instead of being just a smooth pan.
-Navigation spoken instructions being partially cut off at the start of the speech.
-No mileage shown when selecting a route.
