What happens if you drive without clutching?
For those of you who only drive a car with two pedals let me quickly explain what the clutch pedal does. The clutch is the third pedal by your feet and its job is to allow you to change gear.
When you press the clutch pedal down, the plates come apart separating the engine from the drive wheels allowing you to change gear. Bringing the pedal back up re-engages the plates which in turn connect the engine to the drive wheels and off you go again. It is really very simple.
But, what happens if you were to drive without using the clutch pedal at all? Well, this is possible, but I would not recommend it, especially if you have any mechanical sympathy whatsoever.
By putting the car in first gear before you turn the car on will mean you launch forward as soon as you turn the key. From there you can change gear in a very crunchy and unsatisfying way. Please do not try this...
Here is a great video explaining what happens. I am afraid it isn't in English but switch the subtitles on and you'll be fine. But if it starts reading "clutch licking" instead of 'clutch kicking' then be wary. Very wary.
