The likes of Trax and Ford Fair sessions are full of 'Michael Schumachers' who gun it as fast as they can on the straights, flout notice of the 'rules' then wont let you in front of them when you try to move onto the line for the bend (as pulled over to let 'faster' people past) because they are 'racing' then hold you up on then bends
Do a proper track day, much better etiquette
Saying that, have fun and don't worry about trying to be the quickest out there
