It's not as bad as people make out yeah people can get frustrated but there hasen't been a case of a rider swearing at an observer this year I think if a rider falls off and has a quick curse against themselfs through frustration thats fine, was talking to the dad of a brit rider last night and he came up with the good point that swearing happens in every sport (eg Football were any half wit who can lip read can see the foul language some players use) I think we should certainly keep on top of it and punish those that break the rules but so far this season I personally haven't seen or heard of an event that needs such attention.
