I had one yesterday at USA international in the late model. Lots of banging doors ahead put me into 4th after passing an A class racer cleanly on the inside as he ran wide. He then did his best to pass me, I ran the normal line, giving him space if it looked like he was lunging but he couldn't get past, then 15 laps from the end he bumps me twice into the corner, I'm not gonna give him the position as we are racing, lap or 2 later he tries fish tailing me, he goes right down on to the apron so he can try it, I manage to counter steer through it bounced the grass and kept going, he gets alongside and just turns left into my car, very deliberately on the straight. Spun into te outside wall but managed to finish 6th while he retired.
Turns out he has over 200 oval starts but the arrogance of some people who believe its their right to get past because your close to each other is ridiculous. Sent him a message saying if he gives me a good reason as to why he did it I won't protest it.
