France
To become a world champion one needs to push one's limits which is what many pilots do in competitions and displays, a gyroscopic instrument is a safety factor like a parachute if it all goes wrong. Unfortunately one needs 3,000ft plus for a 50% chance of survival with a parachute.
I find it bemusing that an instructor needs the relevance of reducing safety pointing out.
The last french comp I attended as a spectator saw two fatalities and one broken glider on the airfield whose pilot tried to out run a sudden squall which reduced the visible to nearly zero.
