Oh, interesting. I just opened Maps.app on macOS after reading your comment, and the building shapes are finally there, at least in St Petersburg downtown?! The restaurants are mostly correct, too. Something must have changed recently. It wasn't this good even just a month or two ago.

Still no public transit, and still Apple-only (I use a Mac but an Android phone), so still useless for me personally, but it's nice to see it improve.

Though several years ago it was definitely just streets, parks, and rivers.
