Course of action in uncontrolled accceleration scenario

So we've all heard about the problems GM, Toyota, and others have had with their cars going into uncontrolled acceleration. What is the way to react in this situation with a 2 series and automatic transmission? Apparently many cars these days will prevent the brakes from working if the accelerator is engaged, and they will also prevent you from shifting to neutral (with an automatic). Is that the case with BMWs? Can you hold down the start/stop button to turn the car off while it is moving? Can you shift to neutral with the paddle shifters if the accelerator is engaged?



Any tips on how to react in this admittedly unlikely scenario?
