I generally like the 3d view, but I had a hilarious experience up in Marin where I was cresting a hill and planning to take an exit, with a turn I didn't know coming right after the exit.
The entirety of the next 3 steps, precisely what I cared about the most, was totally obscured by the hill in the 3d view.
The exact same hill I was seeing out my windshield. The hill in my windshield was the reason I was glancing at my mapping app for further guidance. facepalm
I also hate not being able to keep north fixed on the screen unless I'm in CarPlay. That just doesn't make sense.
