I learned to drive a standard at the age of 11 on a 1975 Ford and 1981 Chev, both 3-ton grain trucks. The clutches on those things are quite heavy, and I was small for my age; in order to push the pedal in I had to brace my butt against the front of the seat and use both feet to do it. I would then reach over to the 2 foot long shift lever and jam it into 2nd (1st was a "bull low" that you only used if you were fully loaded and trying to get started on an uphill grade while stuck in the mud

), and then quickly transfer my right foot to the gas while doing a "controlled release" of the clutch pedal. I got pretty good at it. I never had to drive the truck very far as I was only unloading grain while my dad was off in the field with the other truck getting another load off the combine; I just had to get it far enough away from the grain auger that dad could pull in and park the next truck for me to unload. I never actually had to change gears while moving until the next fall and by then I was big enough to sorta do it properly. I still had to look between the dash and the top of the steering wheel to see where I was going.
After learning to drive stick on those big old pigs at a young age, any passenger car clutch and transmission now feels utterly slick and light.
I think that nothing beats a great big empty field and an old half-ton truck for teaching someone how to drive - nothing to hit, either stationary or moving, and a vehicle that can be abused without it really mattering. Plus, if you learn to drive standard on a heavier duty transmission and clutch you can't get away with being sloppy and have to learn how to shift and clutch smoothly and precisely. Otherwise, you'll be stuck in neutral and coasting to a stop while desperately trying to find 3rd after leaving 2nd - great fun.
Ah, memories....
