CRX nurburgring lap, frustrated driver

[Pyrolysis]

Watched this vid earlier, the driver is certainly fully committed trying to set a fast lap. Looks like a good lap until he gets held up by a green Focus RS who is either oblivious or doesn't want to be overtaken, then 2 bikes get in his way. Never been to the ring so not sure on "ring etiquette"
