Red Chilli - I don't see your point. I didn't provide any collision risk analysis - just stated that it's low. How many accidents have there been with gliders in cloud? Compare that with the primary causal factors for aircraft accidents.
Shy Torque -sorry, I don't follow your logic. Controlled airspace needs permission to enter (doesn't it?). Commercial aircraft are the primary beneficiaries of controlled airspace. They don't need to be in uncontrolled airspace in the busy areas for gliders and GA. So take them out of the analysis.
What exactly is it that I do not understand about the UK aviation regulations or how GA works? I think you have misread my posting.
Your PM mailbox is also full, so nobody can write to you off-list to attempt to defuse some of the issues that are best handled that way.
