Apple can sleep easy now, Google released Maps for iOS 6 so there's no need to improve the shitty Apple Maps anymore.
I used the new Google turn-by-turn this weekend and I believe that they're the first company to NOT use shitty text-to-speech for most street names. I think they actually recorded dozens of thousands of common street names/words. Only the weirdest names sound like text-to-speech.
Google is mind-boggingly good at what it does.
