Wow, basic laws of physics apparently do not make sense to this guy. He is way to hard in the throttle and brakes, and then wonders why there is no traction left for steering.....Gee, I wonder what went wrong there. And yes as mentioned before smooth transitions will do wonders for the car staying planted.
He probably needs to run some slow laps where he is limited to like 3k rpm's to get the feel for the car and the track. But it does look like he had fun mowing down cones, some tall grass and a few trees!
