S Voice works with google locations My Places.
I noticed that the car driving mode can be activated through setting the Google Locations->My Places->Car option. The Car profile get activated via Bluetooth, Wifi, or location. Driving mode is engaged, and you'll be greeted by the S Voice welcoming screen.
Does anyone know if we can take advantage of Google Locations, My Places services? I know there are other Apps out there like Tasker that does more than what one might need. Since this "Google Locations, My Places" is implemented by Google, it might be more battery friendly than 3rd party apps.
