Cortana - Bluetooth

Had Cortana installed for just over 2 weeks now and the self learning gimmick is now starting to seriously impress me.

I can see little things starting to pop up based on my regular activities. Three days ago, it updated me on traffic delays just as I got in my car.

Today I noticed that Bluetooth appeared to have deactivated as I left my car for work. Can anyone confirm Cortana actually switches Bluetooth on and off based on your usage patterns? I can't remember switching it on this morning; I guess I will have to wait and see when I leave work later today.
