Do you actually use Siri or Maps? Because I find your complaints about them absurd, I use both of these services every day and they work marvelously.
maps has notoriously bad data.
Google and Apple must use the same mapping data, because I see the same errors in both apps. Of course with Google, after I report the error it gets fixed. I can’t say the same for Apple. And Navteq* has more detailed and accurate data than either of them.
What Google has is superb place data. Apple has… Yelp.
*Assuming you have recent Navteq data. Not the nav system in your car that hasn’t been updated in 2 years.
