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.
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.
