what alternate reality is this? Google Maps has never stagnated ever. Tons of new features have been added every year since it was first created. Go read the maps blog posts, watch the google i/o videos, or just search for it and you'll see 10s of thousands of articles listing the new features from each year.
It's our lived reality, not the SWE-centric reality. We don't really want new features, we want the existing features to work better. The voice output on Google Maps is simply bad. It calls out turns when there are other available turns before the one you're supposed to take, and doesn't say anything to disambiguate. It draws which lane to be in for your exit but doesn't call it out. It doesn't say what you need to know for compound instructions (e.g., exit followed closely by fork). You must look at the map to be able to follow the instructions. Apple Maps does these things better and that's why we prefer to use it (with screen mirroring to the car).
And yes, we even like the 3D view. It helps provide context faster than the 2D view, even if it doesn't always render the best information. Every product has room for improvement, and Apple Maps has been improving. Google Maps isn't usefully better now than it was in 2015.
