If you've ever taken the bus or subway home after drinking too much at a party, you know how tough it can be to get off at the right stop -- you may fall asleep well before then. That shouldn't be an issue if you're using a recent Android phone, however. Android Police has noticed that the latest version of Google Now on Android lets you set an alarm that wakes you up shortly before a favorite destination comes up; you can safely catch some shut-eye knowing that you'll still be home on time. There are third-party apps that offer similar reminders, but it's good to have a built-in safety net when you're not entirely sober.
