What I can't stand about Google Maps is how it hides so much stuff if you're not zoomed in 1000x. The worst time was when I was trying to trace a 100km long logging road in northern British Columbia to get to a provincial camp site on a lake, but as soon as I zoomed out to get a broader picture it would disappear. Even though that was the only road within a 15 km radius. Nope, you can only see a 1km section at a time, and it's so thin and low-contrast that it's barely visible.
There are also some really bizarre choices in how the UI works. I don't remember exactly, but I believe when you search, you get a wildly zoomed out regional view, and then when you click on a specific result...you're still stuck at the very zoomed out view. So in order to see if you clicked on the right result, you have to pull the map waaaaaay in.
I just found myself baffled at how bad the usability was. Did the people running Maps actually watch people using their product?
I haven't compared Google Maps to a dedicated device like a Garmin. I wonder how that would do.
I fear that in particular for local mapping, as right now outside of OSM the only companies putting serious effort in maps are US and China based (to my knowledge at least)
As someone who enjoyed smaller screens, the app started getting cluttered with attractions, reviews, and various icons in way of UI and map elements.
