I learned on the hand clutch John Deere's and Alice Chalmers before I was big enough to be able to push a clutch peddle in.. When you got big enough to pick up a bale of hay, you got DEMOTED!! Double clutching just came naturally, as part of driving?In the last 60 years I have driven about every combination of transmissions built, but the most confusing were the 12 & 16 Spicer's, a 3 or 4 (respectfully) speed pattern with 2 air shift paddles, where you had to go thru neutral on every shift. Do not forget where you are!!!
All my children learned to drive a stick, but were amazed when I float shifted, not using the clutch, their cars. The fly by wire throttle peddles hampered that ability as you cannot "feel the pump" in your toe as easily.
