There was some unsafe passing at TMP as well. One fellow in intermediate in particular had a hard time understanding the rules. He stuffed me in 1 and then couldn't manage to complete his turn without using 99.5% of the track, which left me in an awkward position. Later I was following another rider into 9. The same idiot comes by me and tries to pass the fellow in front, but again can't leave enough space. I saw the other rider try to turn in, see Mr Doofus exactly where he needed to go, then straighten it up and ride off the track. After witnessing that I suggested to the starter that they might like to have a chat with him*. Black flag next lap. As far as I know he behaved himself after that.
Probably I have some of this on video I will check.
