I think that Stewart actually DID expect the kid to jump out of the way as he was clearly trying to “buzz” him...funny ha-ha! Problem is, the “professional driver” lost control of the vehicle and mowed him down instead of brushing past him.
How anyone could come to another conclusion after watching the video is beyond me.
I’m not going to say anyone definitely “did” this or that intentionally, and am speculating based upon personal opinion only. But, to me there is the appearance of something along those lines.
