i dont think its that terrible and i've had my car for just over a week. it doesnt run if the car is still cold, so there is stuff in the car that determines when to run it or not.

As you've discovered it won't shut the engine off under certain circumstances such as when the engine is still cold, as it needs to warm up as quickly as possible for emissions reduction. It won't shut the engine off if the ambient temperature is too hot, or it may restart the engine before you release the brake. It depends on how hot the outside air is. There is a gel in the air ducts that freezes/gets very cold while the AC is running so that when ASS shuts the engine off the air vents keep blowing across the gel to keep cool air coming into the cabin. If the car is still stopped and the gel has warmed, ASS may restart the engine to provide cooling.
If it's too cold outside the same things can happen, as vents will continue to blow warm air until it's exhausted, and if the car isn't moving the engine may restart to provide heat.
IIRC, if the trans is in "manual" mode, ASS won't activate.
ASS may also not activate if the driver mode is in sport+, but I'm not sure about that one.
Seems BMW spent some time working out the little details on implementing ASS.
The part they need to work on some more is with the AT. Once the car comes to a stop there is still load torque being applied to the RWD, and thus there is some compression of the front suspension. When ASS shuts the engine off there is no more torque on the drive line and you can feel the rear suspension drop down. It's an odd sensation.
I don't use ASS, not the BMW type at least.
