I have to admit I heard some rather choice language and saw some pretty horrendous track jumping and general driving - yes we all get the red mist down, and yes we are not all great at getting past others cleanly - but I think shouting sorry if you do cock it up goes a long way. If I hit someone I apologise - its not difficult and stops half the frustration we feel when we get hit - in turn stopping half the arguements! Theres some quick drivers that are poor at overtaking, but more importantly poor at apologising if they hit you or get it wrong - and as you say - its supposed to be fun!
