Er... the BRCA do not make rules, you, the members do. If you want something done about this then get a proposal (with seconder) to the 10th Off-Road Secretary on the appropriate form at the designated time. Turn up at the AGM, explain the proposal, discuss it and vote on it.
At the last AGM nine people turned up at the 10th Off-Road AGM. So, you'd only need to find ten like-minded people to go to the AGM and your new rule would be passed if the same turn-out happens this year.
The BRCA do not make rules, the members do. If this is what you want then follow the procedure, turn up and vote. I realise not everyone can do that, but that's how it works and it means any member with enough support can get the rules changed. HTH
