I personally have tried to edit my address issue it 10+ times already, but they keep rejecting it. It would be good to know based on what they get GIS/map data because then I could try to edit at the source.
It doesn't seem that the reports go to someone with local knowledge or within that country. And someone from abroad won't care about the local nuances that make a difference.
I always assumed that Google used location data to help routing. Especially location data from people not using any navigation. But these stories suggest the system is a lot dumber.
for Google Maps
you click on a point and hold it until a pin forms
In the pin popup there's the GPS co-ordinates
Click the GPS again and it loads the point not as decimal GPS but...
47°26'46.8"N 122°17'51.4"W For KSEA Seattle International Airport's departure's drive
