when you stop at a traffic light or whatever, and you are going uphill, autostop kicks in, and when you release the break to put your feet on the gas pedal, the car just rolls back. That was a big surprise for me first time it happened. Now, i know it should do that but not that much it did. I think I rolled back a foot or more and the guy in tha back got scared... he flashed me his lights... since then, in this situations, I use handbrake gently, just enough to keep the car there until I have enough gas on.
