I love my DCT, especially when it lags for a second or two before the engine red lines and I shoot out into traffic at light speed. Fortunately the car has really good brakes so I can just jam on those real quick before I crash into somebody. There's nothing like jamming on the brakes real hard when you've just had a big meal or have to pee really bad.
The best part of the DCT though is how it's efficiency increases with ambient air temperature. The hotter it gets the more reluctant it is to downshift which causes the engine to stall at stoplights after leaving the freeway and that saves me fuel! As they say, an engine not running burns no gas...or something like that. At least it has push button start so restarting the engine is as easy as punching the dashboard.
I love my DCT, yeah, just love it.
