Why Must I Sign In, Google Maps?

Brian S Hall describing his aversion to the new Google Maps iPhone app:

From the moment you open up the app, Google asks you to sign in. Because, apparently, you can’t really get from fucking point a to fucking point b without signing in to your fucking Google account.

This sums up my feelings about the new Google Maps app. Why must I sign in to get directions? I don’t need to sign in online to get directions. And why can’t you access the contacts on my iPad? Do you seriously think I am actually going to retype all of my contacts into my Google account? Give me a break.
