I did not expect the numerous responses to this incident and will post a video if I can when my crew sends a link. It is a Contour camera and he is struggling with getting it loaded to a site for viewing.
I have a history of racing in in both high speed and low speed cars with much faster classes in a mixed group when I have been the slower class. I also have a history of not taking low percentage passes. In this situation it was not low percentage and if I had to do over again I would have made the pass. The driver made a very late wide apex and I had plenty of room initially. Even in the race with Alex later that day, if I did not know where he was, I could of easily taken us both out for some very late passes in a few brake zones. So a driver should be aware of what's going on around them.
I did approach this driver to discuss the incident. They said they were committed to the corner and did not see me or the flag. I asked about the passing flag that I swear the corner was waving like a yellow where a car was broadside in the corner. They were waving it hard.
So it is what it is and it happens. But I would make the pass again as the door was readily open to make the pass. Some people drive race cars and some let the race car drive them. I am a relaxed driver and typically know what is going on around me at all times. Like my original post said. My weekend could have been worse.
