looking at that gif, id be worried about the gap in the wall too, cause if truck wasnt there it almost looks like he would have missed the tyre wall and gone through the gap...
it was a horrible accident, rain fell, inters at the end of their life so prob dispersing less water, and a fast sweeping turn...
also the green flag surly shouldnt have been there
hmmmmaybe not, looks like the wall folds back, just not sure how far
