I remember driving the hay truck one year, could reach pedals lol.Same as OH2BBAD likely under 10 driving the tractor while all the men would load the hay wagon. One of them would help me make the 180 turn at the edge of the field and I just kept it straight ahead til next turn. Some what like Nascar.
At 13, my dads friend would let me take his bug around the back roads. At 16ish one of dads friends with a Celica said take it for a drive, don't shift to the next gear until you get to 6000 rpm.
