Part 4: The '80s
The clutch pedal and clutch override become more important as we go up the brackets. There's a whole list of cases for learning how to use the clutch, like pulling yourself out of a ditch after you've crashed to a dead stop, getting yourself up to the powerband if you've had to go low in first gear through a turn, deploying the clutch while in a jump so your driven wheels' speed is only affected by the ground when you land, etc. etc.
It might be easy to forget that it's there if you're not used to it, but the clutch pedal is a powerful tool if you know how to use it.
