Google might be wrong, or a farmer might be trying to prevent people from using what is legally a public footpath. They sometimes buy the land and then want to take away legal public access to it.
Google maps doesn't correct shit. I've tried multiple times to get a nonexistent road (literally, i took geotagged photos showing this "road" is untouched brushland) that cuts through my parent's place removed, and they never responded or did anything about it.
I’m fairly certain they crowdsource the info. Their initial scan gives them a baseline, then they wait until x number of reports all conferring with each other to have the system either kick it up for review, or make the change automatically if possible.
It took YEARS for me to get Google Maps to correct the location of a local bus stop. It showed up on the wrong street, which screwed up walking directions. They finally fixed it when I submitted a photo of the bus stop along with my report, even though it’s exactly what you see if you check the recently updated street view in the exact location I had been submitting error reports. 🤷♂️
How do you do that? A few streets in my parents' town are not up to date. In 2021, the views changed to what it was in 2012. But only for like 3 streets.
