I mapped my way to several familiar destinations to gauge whether the trains and routes Maps suggested were the quickest and most efficient ways to end up at my destination, and they were. Bonus time-saving feature: Apple Maps shows you where subway entrances are in flyover mode, which is incredibly useful. Grand Central Terminal has several entrances, but if you don’t know where the closest one is, you could end up walking several blocks out of the way. Now entrances are helpfully marked “Entrances” (so simple, so necessary) in Maps.
If there's one thing I'm excited about iOS 9 this year, it's the HUGE improvment to Apple Maps. Now how about you start unbundling all these app updates from their respective OS updates so we can see a steady upgrade / bug fix over the months instead of waiting a year? Or better yet, installing a operating system update just for app bug fixes. Thanks!
