At least here in Sweden you have much more detailed POI info in the countryside, like rune stoned and such. In Google Maps they can be impossible to find, and even the small path leading to them do not appear.
I thought the same as simonw, I guess the confusion comes from that I would interpret POI search as being shops in towns. Indeed, things like runes and other countryside things with trails leading to them, gmaps is terrible at. I guess they just don't see the money in it, so it's up to us to map it ourselves.
