Wow - John is flirting dangerously with the old manual vs. PDK debate.  His is the most diplomatic and soft-spoken approach I have witnessed here.  Good going.  I am with you, of course - but sadly I do not have the answer to your brilliant and important question.  I would hope you could turn it off because if you shift too quickly it might actually accelerate the car more than you would like.  (Of course any automated control of the throttle with INCREASES revs might be considered dangerous not just intrusive)
