Actually, from everything I've read, it appears Google refused to allow Apple to implement those features (see, for example, http://allthingsd.com/20120926/apple-google-maps-talks-crashed-over-voice-guided-directions/ http://allthingsd.com/20120926/apple-google-maps-talks-crash...). Google wanted to keep those features exclusive to Android maps.
