The DSG can seem to be a bit dim at times, however it's just trying to guess what you want from it. It's possible to wrong-foot the DSG inadvertantly, when it thinks you're planning to sit where you are for a while, but actually you want to set off, and you give a throttle demand that the DSG doesn't quickly respond to, then the revs rise, the DSG seems to dump the clutch and "Yoink!" off you go with an uncomfortable lurch. I have found I need to think slightly further ahead, release the brake, feel the clutch engage, and then hoof it. However as I always put my DSG in neutral when I come to a halt, my putting the car in gear from neutral lets it know what I'm up to. Sometimes, I switch from neutral to drive and back to neutral again, if the gap to enter traffic isn't quite right and I need to skip a car or I'm having a senior moment, and that will usually confuse the DSG and I get a lurchy getaway as a reward.
