As far as I can tell, that feedback goes into a black hole. I've sent many corrections there, not a single one has been adopted, including ones where entire streets didn't exist (i.e. they exist on Maps but have never existed IRL).
In the city I used to live, they had to put signs up at the entrance to a street, warning people to ignore Google Maps. It tried to route people the wrong way up a one-way street, and the government had failed to get Google to fix it.
