You are welcome.
The theory is that Tiger started moving into these S-curves going down hill to cause him to exceed the control necessary to stay on the road. In that situation, he hit that median strip; wiping out the sign as his car went into the oncoming traffic lanes. Then he went off the road, missing a huge tree but did wipe out a smaller tree that caused the car to flip over end-for-end to rest on the driver’s side. Do you suppose he did it because of excessive speed or an effort to miss a car driving on the wrong side of the median strip? The distance that sign was thrown would be a clue to his speed. That there were no brake tracks says it was a instantaneous loss of control. The place where he lost control was near a huge set of trees where their shadow could have obscured the curve in the road, or an oncoming car on the wrong side of the median.
As soon as his vehicle hit the curb/center divider, there should have been post impact skids as his vehicle crossed into the southbound lanes. Where are they? He should have been standing on his brakes...Yet no post impact skids were visible.
