Looks like a normal turn to me. I don't see the tires once turn towards him. The dude is in the middle of the road like a nutcase. It's not like Stewart was drifting towards the right.
Normal turn? He's not supposed to be turning at all. Nor is he supposed to be that high on the race track. Nor is Mr. Ward (RIP) supposed to be on the racetrack. It's all a fucked up mess that cost a young man his life. Racing is dangerous. That's a fact. I ended up in the ER racing myself at a local dirt track 2 years ago.
You see a lot of guys burp the throttle a lot on caution laps, myself included. Do they do this to show out like most people think? NO! they do this because the worst thing for a race engine to do is run at idle speeds. It causes the rear end to slide out slightly, also helping to keep the tires warm.
