One of the best pieces of advice I ever heard was “You can go down a hill too slow as many times as you want. You can only go down a hill too fast, once.” Great video man.
I remember being a trainer for Schneider going down these hills by myself and with trainees. I remember one "super trucker" coming across the horn poking fun that "Schneiders scared, can't hit the hill without taking a piss, and checking brakes" i looked at my trainee and said "just wait and see" we got about half way down and Mr super truckers brakes were literally on fire as he was in a runaway. We checked on him and an important lesson was learned by everyone.
