And not just motorsport champions either, sometimes its people with a little excess money that go out and get their private license, buy a helicopter and away they go flying for the next 2 years (well at least where I'm from) without any further training or scrutiny.
Its quite amazing how many private helicopter owners that have bit the dirt from doing stupid things in these machines.
As a commercial pilot you are under the watchful eye from Ops managers, Chief Pilots, fellow company and non company pilots, engineers and of course the customers also and if you do something wrong you are told about it in some form or another.
Maybe its not the low flying rules that need addressing.
