I think back to when I was learning to drive 27 years ago on our Dodge Omni and my dad would yell at me, "Get your foot off the clutch!" every time I rested my foot there. "Unless you're shifting, your foot doesn't belong on the clutch pedal while moving" I was told over and over. Resting your hand on the shifter while driving was another big no-no.
Not sure if it really matters to the life of the clutch or not but to this day I've never needed to replace a clutch on any of my vehicles....including that Omni that had almost 150k on it when we sold it.
My Dad taught me the same thing, I taught my son the same thing, except for the hand on the shifter.
