I've used this feature a few times, and I'm actually surprised how quickly it will kick in -- I've had it stop at a light probably only 3 minutes into my commute (though it was a warm morning), and definitely the car was no where near warmed up according to the oil temp gauge. Apparently its idea of "operating temp" is pretty low. I did have it restart at least once when I think it concluded the car was getting too hot. I'll be curious to see if it will shut off during the Chicago winter. This is kind of a nice feature for my commute, as I have some lights on my commute that are very long (~ 2 minutes if I just miss them). It does restart pretty quick.
