In the world of the F1 semi-automatic and seamless gearbox's, of course, there
is no need for the driver to even think about this – everything is
electronically controlled! All the driver is required to do is to pull
gearshift paddle on the back of the steering wheel when he wants to change
up or down a gear, and the electronics controlling the gearbox and clutch
do the rest. The advantages here, over and above the fact that the driver
can keep his hands on the wheel at all times, is that the whole process can
be done in a split second (much quicker than a manual clutch could be
operated)
and also that the wear on the clutch pads is less because it is never held
half-on, and so this increases reliability.
當然，在F1半自動和無縫變速箱的世界中，駕駛員甚至不需要考慮離合器(起跑除外) -
一切都是電子控制的！ 所有車手當他想要降檔時,只需要在方向盤背面拉動換檔撥
片，剩下的控制離合器和變速箱的工作由電子設備完成。
這優點，除了駕駛員始終可以將手保持在方向盤上之外，整個過程可以在瞬間完成
（比手動離合器操作快得多）以及離合器片上的磨損較少，因為它從未保持半開(半離合
狀態)，因此而提高了可靠性。

Changing Gear
When a driver changes gear, he does not operate the clutch himself.
The driver flicks the paddle, and the ECU cuts the ignition. The clutch
is depressed electronically and switches ratios. Since the introduction
of seamless-shift gearboxes, that all happens in 0.005s...
換檔
當車手降檔時，他自己不操作離合器（起跑除外）。
車手輕壓撥片，ECU切斷點火。離合器被以電動方式壓下並切換齒比。自無縫變速箱
推出以來，一切都發生在0.005秒 ......
