I can't really relate to this experience of the DSG, and I wonder if there's a bit of antagonism between the driver and the car, that stopped the driver working cooperatively with the car and gearbox for the best driving experience. I have a mental image of JG pulling away from the lights angrily muttering "Stupid car!". (Though I agree, the Skoda manual gearboxes are a delight to use.)
Yesterday I was visiting a loved one and I found myself on a slope at a set of traffic lights.
As usual, I put my DSG gearbox into neutral when stopped, applied the handbrake, and the engine cut out with the stop/start system and I took my foot off the pedals.
Watching the lights, as I saw the lights preparing to change, I put my foot on the brake, put the DSG into drive, released the handbrake, and a moment before I wanted to move off, I released the footbrake.
The engine promptly started, and as soon as I felt the clutch connect and the car move slightly, I applied the throttle. There wasn't so much as a hint of the car rolling back.
It's not entirely dissimilar to driving a manual, only the clutch is controlled through the brake, rather than the clutch pedal. It's all effortless and drama-free, but you do have to work with the car.
Years ago, I had a Ford Orion with a carburettor. When I swapped that for my Rover 420 with fuel injection, I noticed that, unlike the Orion, there was a distinct lag between applying the throttle and the fuel injection system responding.
It wasn't a big delay, but it was noticeable, and so I adapted my driving accordingly. If I hadn't adapted, I would always have misjudged my exits at junctions.
It was much the same when I swapped from my normally aspirated petrol Rover, to a turbo diesel. The car did not respond to throttle in the same way as the petrol car did, so I had to adapt my driving style accordingly.
