To be honest, at least when looking on my phone, I found it to be a little too detailed. A thousand examples of what we already know. In my head I was playing dramatized commentary: "Gee, the POIs are round but the areas are not, they're square. And they have been adding buildings. Oh boy, could they really? Yes indeed, they seem to be following building contours. My gosh, that is so smart! And look, here as well! And (gasp) another example here!"

Maybe I'm too much into openstreetmap and these things are normal to me, but "beautifully" detailed was not my experience. More like google fanboy showing off.
