Sometimes a person guns it to avoid an accident, if the guy was charging across the track, which it looks like he was, Stewart might have gunned it to be ahead of him
but, the car was angled to the outside of the track a little
spin in the dirt?
try to accelerate too fast?
.
.
or aiming to scare him and he misjudged it?
I have doubts he meant to hit him...
Stewart probably just meant make the kid poop his pants but misjudged and Stewart will pay
Stewart should be banned from racing
he is an ass
