Google Maps has had glitched-out building outlines overlapping rivers in my city for years. I don't trust it at all. Citymapper is nice for public transit directions in cities.

But then, another Google product, Pixel Watch, has the bonkers default that if you just take a walk, like I normally do on most days, it considers that a "workout" of a dedicated type "walk" that needs to be tracked. It would vibrate rather annoyingly too. So basically every time I go outside to grab a lunch, that's a "workout"? But at least you can turn that off.
