I'm still in awe Apple is willing to trash its own previously sterling reputation by sticking with this horrendous Maps app. If Tim Cook has any balls AND was genuine with his "apology", he would have pulled Maps off iOS 6 when he apologized and reinstated Google Maps, allowing for the Apple Maps app to be worked on and "re-introduced" when it was actually "ready".
It's one thing to admit a mistake and DO SOMETHING about it, it's another thing entirely to "apologize" and continue doing the same thing, i.e. NOTHING in this case.
Don't give me this "Apple HAD to release Maps since it can't improve it without crowd sourcing" rubbish when it's clear Apple hasn't been responsive to user corrections in any way that could be considered an acceptable anyway. As I mentioned previously I've submitted a couple dozen corrections myself since I bought my iPhone 5 months ago and NONE have been implemented so far. From reading this thread it seems my experience is not uncommon.
It's obvious the problem with Maps goes well BEYOND just faulty data, there is something totally broken with the app and its development, from the responsiveness to user corrections, implementation of new data, sorting and prioritizing the mountains of data coming from various data providers, which often contradict each other, and the entire user experience. Out-dated data is a HUGE issue as well.
Going from Google Maps to Apple Maps is like going from a Mac to a PC...running MS-DOS.
What Apple needs to do is to either complete revamp the Maps app i.e. rebuild it from scratch OR completely scrap it and go back to Google Maps. Seems like the latter would be the best (and perhaps only good) choice.
