Take a paddle shift car round a track shifting it yourself. Then take it round again letting it do the shifting. I'm pretty sure you'll be quicker. Chris Goodwin (chief test driver for McLaren) says the fastest way around a track is auto mde. Much as I love manuals, DCTs are superior.
That's never been the point, David. No one is or has ever argued that DCT's are the faster way around the track or a straight line. But for those of us that don't care about tenths of a second (or seconds for that matter), than there is no contest between the two.
