That's one exciting finish for ALMS after so many hours...
Half way thru the video, my bet was on the Porsche to win. The Vetter is obviously faster, but he lost his patient and made more mistakes. Both of them are being rough. Porsche deserve to win judging from the distance while exiting the 2nd last corner. He was too behind to pull any move, other than bumping the car in front which he did. However, the Porsche was obviously violent to drive him to the wall afterward.
