You can see he pulls up a bit too far for his burnout, simple enough to do at an unfamiliar track. Then the big mistake comes about when the car starts to walk sideways, he should have let off both throttle and brake and rolled straight. It happens fast in RWD high hp cars, not sure how much track time you have, but it really is an easy mistake to mkae. He only corrected a little bit, but the car hooked and shot him at the wall.
To give an idea of how fast it happens, second gear burnouts are usually around 80 mph at the rear. When that hooks, picture your wheels not being perfectly straight. Yea, not good.
