Samsung Galaxy S4: what application is responsible for "Time to home" notices? On my Samsung Galaxy S4, I constantly get notifications "Time to home XXX minutes". They are not only useless for me, but also apparently some app is accessing my location, internet, and is draining my battery.

I couldn't find out what is responsible for that. What app is showing that messages, and how to turn it off?
Google Now, you can disable in the settings of the "Search" app.
