In the most part 1/8th off road nitro racing in Australia is run under the AARCMCC governing body, and within these rules you are not permitted to use offensive language whatsoever and most SEQ clubs have made it a mission to stamp out this form of behavour from any driver / mechanic / competitor. If you hear anyone using bad language and others around you will confirm who the culprit is then report them to the race director who should then take the apropriate action.
Whilst marshalling it is prefered that you watch your section of the track but we have all at some time been caught out watching a good battle for the lead and missed a car on its roof next to our feet.
Good marshalling is unfortunatly not rewarded that well at club or state level maybe its time for a change as i know of several people who work their buts off week in week out and on the flip side there are others who have their arms painted on and backsides stuck on the milk crate.
