I 100% agree Lead Balloon, I think the problem lies with some pilots that they do not have a clear-cut go/no-go plan in their heads, they look out and think, "yeah, I can make that". On the roads you have a sign with big black numbers with a bright red circle telling you "this is the speed limit", a driver can of course go slower than the limit, do the limit or choose to exceed the limit, no power on earth can control the choice a driver will make. A VFR pilot also has to make a choice, but either through lack of training (VFR minimums drummed into them), lack of experience (gee I almost died then! I'll never do that again) or lack of responsibility (I'll do what the heck I want) they still fly into situations where they end up in IMC. Certainly more regulations are not the answer, clearer regulations maybe?
I guess some action will be taken by the authorities because as we know all Australians need a regulation before they can choose to obey, ignore or work around it.
