Just saw an R8, in traffic, stutter twice and almost cause two accidents in quick succession. Why? Looked back, noticed the driver clicking his paddles. Okay buddy, you're in stop and start traffic with your S-tronic transmission; what you want to do is put it in auto and let the computer do the work.
I can shift my pony whenever I want, comfortably. I don't have to rely on a boring autobox in bumper to bumper traffic, or contend with a sporty dual clutch system that always wants to race.
Okay, so lower end DCT's geared for city driving overcome this fault. But, y'know. It's the small victories.
