Agreed on part of trying to be predictable. There is a distinct skill in learning to "read" a car spinning in front of you (I have perfect race video of this). As the race driver who is spinning, you can't be thinking about that. You're too busy looking out the windshield, then as the car comes around 180, you're looking at the rear view mirror, then out the windshield again, trying to regain control of the car.
"Both feet in ?" I have never agreed with that teaching. It might be safer for new drivers. I don't talk about it unless asked at the perf driving school. The brakes do you absolutely no good when the car is side ways. If you're rolling frontwards or backwards, then ride the brakes down. Don't lock them up. All you're going to do is flat spot your tires.
I can't count the number of times I've had massive spins and drivers have come over to me afterwards and said, "Well, you ruined that set of 4 tires, huh?"
"Nope.......didn't lock up the brakes. Tires are fine. Look for yourself."
BTW, When are we going to have that racing school we were talking about?
