Here is the raw video from Live Link

What you see...
1) Tony Stewart is in car #14 while the other driver is car #13.
2) Both cars 14 and 13 are turning and 13 does a 180 and wrecks. The driver in Car 13 gets out and starts pointing at Tony Stewart in Car #14.
3) The camera thought is was Car #45 because the camera follows #45 briefly.
4) When the camera goes back to the driver on the track. That’s when you see Tony come right up on him and hit him.
5) It’s hard to tell from this angle, but if you look at Tony’s front two tires.... They are turning towards the guy and not away.
It’s looks deliberate from this point view, but I may be wrong?
One might expect that tire angle on dirt as you turn into rear tire slide out as a normal means of racing at full speed on dirt.
If he turns the wheels to the left, the car spins and hits him for sure.... if he turns them to the right and burps the gas as he did, possibly it spins the opposite direction away from Kevin. It looked to me that is what happened, he made the only evasive move possible, after the front wheels passed Kevin, you could see the wheels twitch to the right.I know its hard to understand, but these cars drive opposite from what you think. When racing at speed, they go around the corner sideways with the front tires turned all the way to the right, but the front tires are not really directing where the whole car goes, just stabilizing the front end... the driver is controlling where the car is on the track with the throttle, the right rear tire is bigger than the left rear and if the car is going around the corner and your not turning sharp enough and headed for the wall, you keep those wheels turned to the right and you hammer the gas pedal... When riding around at the slower speeds under caution it is much harder to aggressively turn the car to avoid anything...
You can’t get anymore conclusive than live commentary “Tony hit ‘em!” Seriously, the guy was showboating for the fans by coming out of his car. It’s no different from players that charge the mound, except speed and steel hurt a lot more. But it looks like Tony made a very bad decision to try and scare the guy.
If Stewart was going to avoid someone running up on the right side, he'd have cut the wheel right and hit the gas to slide the back of the car left and miss him.
Poor visibility, both from the wing and a suit almost the same color as the track surface would limit Stewart's chance to react--as well as not expecting anyone to approach the cars in motion that closely.
I can't see an intentional hit, and I think the move was an attempt to slide the rear of the car away from the driver on foot.
