Yeah no helmet, looks like it might have been a flipoff instead, or a attempt to punch. These cars aren't wide anywhere except the wing.Hit the gas to avoid the helmet strike? You mean the helmet he was wearing while lying lifeless on the ground? I can see why you would think that...
I think gunning it and swerving a little was to dodge the punch or whatever the kid was trying to do. Then again when you hook a 150lb (minimum) person on the wing of these tiny cars, the car is gonna swerve.Look at the blue car swerve a little as the guy runs on the track, Tony's swerve might not have had murderous intent.
As dark as the track was, I have doubts whether Stweart even saw the guy there, in his black firesuit. But the video is pretty clear, the wing clipped the guy which accounts for the sudden direction change of the car, not anything to do with steering which as you said really doesn't have all that much influence there.About the engine sound, for those that do not know, you steer with the throttle coming out of corners on a dirt track. Turning the steering wheel does little to change direction of the gar without added gas. Also, the right side of those type of cars have horrible viability due to the design. Not saying that is a good thing, but rather how it is.
Only Stewart will know what was in his heart when it happened.
