I'll give you both drivers explanations.
Mustang driver thought that the car to his right was turning in on him. His reaction coupled with the crest of the hill started the spin counter-clockwise. I believe his attempt to counter-steer and then the back tires hitting the grass cause the clockwise spin.
Del Sol driver said the brake pedal went to the floor, which caught him by great surprise since he had brakes up until then.
