FWIW, I've read elsewhere that Google has had 1000 contractors in India cleaning up map data for 5 years. People using it isn't going to clean it up with "moaning". Apple is going to have to throw a LOT of resources at fixing this.
More people moan the more likely it is Apple will throw resources at it. It needs people using it and complaining to show where the data isn't working.
From trying it there does seem to be a reasonable level of detail.
I don't of course just mean the bug reports, I mean every email going into customer support, every snarky comment directed at Apple and so on. It'll encourage them to dig deep, hopefully.
There's a "report issue" button if you hit the bottom right corner of the map. It allows you to drop pins where issues are and gives free text fields to enter information.
