There's a neat Easter egg hidden within the latest version of Google Maps, which we first saw over on Android Police: If you nag the app too much, it'll tell you off.
Give it a go - open Google Maps, enter your destination, load up Navigation mode, and ask it: "Are we there yet?"
The first time you ask, it will helpfully give you an ETA.
After that, it will default to a simple "no."
But if you keep going, the app eventually resorts to an unusual threat: "If you ask me again, we won't stop for ice cream!"
