In the US its pretty easy to submit corrections. I've submitted a few corrections on US public lands but now I usually don't bother and just update open street map instead.

I have submitted many glaring fixes, often multiple times for when it continues to be a problem, over months... and almost never is it fixed.

I once submitted a correction for the exact location of a public park. The correction looked like it was applied, but when I looked later it had been reverted.

The data pipelines for maps can be very long - certain changes might take 6 months or more to be applied, because the computation required to rebuild certain things is massive, and it isn't worth doing simply because some street edge moved by a few centimeters.

This wasn't a few centimeters - I had trouble finding the park because Google had it a couple of blocks away from its actual location.

I think this is the right approach. Why do free ground-proofing for a for-profit company? (Who is also so unresponsive). Better to submit fixes to a community project.
