Dual Clutch is great for racing where it can be rebuilt on occasion. Not so much for street use. People don’t like rebuilding their transmissions every couple of years.
People don’t know how to drive them. They treat them like automatic transmissions. They’re not. They are manuals. So people get freaked out by the initial shudder. They do things like creep along at 2 mph like an automatic can do with its torque converter.
They do things like take their foot off the brake on an uphill incline like you can do with an auto while the torque converter keeps you from rolling backwards. The way people drive has a lot to do with the problems people have caused with dual-clutch cars. They are not as forgiving as an auto, just like conventional stick shift is not as forgiving.
I would kill to have a dual-clutch in my Challenger. I would love it.
