Well, no.
I watched the video, and that didn't happen.
In any type of racing, the person lower on the track and/or ahead of the other car has "position,' which means the guy above and/or behind needs to beware and give way.
This particular type of car swings the rear to the outside of the track entering and through turns. The kid was where he shouldn't have been, and if he had any amount of wheel time, he knew that.
Stewart did nothing wrong which would have put this guy "into the wall."
And he didn’t kill him on the next lap around the track yada yada yada...
