Good day and welcome to the forum!
Speaking from past experience, smaller towns have faster voting times than a crowded city. There are few exceptions: isolated locations like in the Pacific islands. Review bonus location can be used to add an additional location to review at a time, maybe people here can do that in your area.
There are other methods (not accessible to players like us) of game object input that are less tied to objects/places like Testing New Wayspots in Pokémon GO - #2 by NianticTintino . This one assumes there are streets and bus stops, so is still tied to some form of infrastructure.
I’ve also asked myself with how we can solve this problem. The solutions I see is to have a personal game object for each rural player or make change outside. The former is subject to each game’s development team. The latter can be achieved with a community, funding, and coordination. POIs are tied with real objects/places, it is a trend that changes only when reality does too.
