I tried to explain that if you corner a car too hard, it may skid. “Corner” an airplane too hard, it may stall, spin, and crash, in that order. One day, I had him do a “high speed” (40 knots) practice abort on takeoff, and he stomped on the brakes—but mashed the left one harder than the right. We got pretty darn far left of centerline—I think I could read the words on the vending inside the FBO building—and came to a stop.
