It’s so sensitive that the engine will stop while the car is still moving before coming to a complete stop. I end up turning the system off, especially in Toronto traffic which is sadly where most of my driving happens.

On the the flip side, when the engine starts back up, it’s much smoother sounding than the A4 was.
