I am the driver of the Porsche in this video, what the view that he is showing fails to show is that with him being so tight to the inside on the straight approaching the corner that he started braking so early on the straight that by the time we had reached the end of the straight and the turn in point for the corner he may have had at most his front bumper next to my back bumper due to the difference in speed and I figured he would realize that there was not room to make the pass and back off.
He did have a good run but I knew there was no way with his location on the track that he could hold that inside line and his speed and sure enough he because of his line was forced into braking early enough on the straight prior to corner entry that he was not able to complete the pass or even stay side by side before turn in. Some passes at high speed you can pull off and some you cannot and in my opinion it was a bad decision on the OP to try the pass he tried with his position on the track.
It was definitely a ballsy move by the OP and in no way did I intentionally make contact but with so many aggressive drivers making "forced" passes it conditions you to hold your line and position with perhaps to much gusto at times but that exact same situation I would do the same thing. There was not a clear car width passing lane without me moving over to allow him through.
We did run pretty hard for a few laps and had some fun nose to tail racing.
