The next 90 or so days in the US aren't going to be fun for the stock market. The mid-term elections are going to have investors running scared that the "wrong" people will win and someone will tax away all the profits.
I believe that most modern automatic transmissions are dual-clutch simply because the design is better. You get faster and smoother shifts between gears. While it's nice to pretend I am better at shifting gears than the computer, I am 100% certain it's faster and better at deciding shift points, especially with a gated gear shift that is going to take forever to get between gears. I probably can't beat the computer with paddle shift either.
