If you look at the previous threads, it's not the hi-viz vests that are the root of the problem, it's the management stance that says "hi-viz vests are good, other airfields have them so we must too" is the problem.
A lot of people don't seem to be safety aware but how many people do you see getting chopped up by props or knocked down by fuel bowsers on GA airfields? It is a semi dangerous environment but we are aware of that and if we have people with us who aren't it is our duty to look after them. This doesn't involve placebos like hi-viz vests which can lull the uneducated into a false sense of security. It involves an understanding of potential problems and what steps to take to avoid them; eg don't walk towards a rotating propellor, don't walk in front of the fuel bowser (just like you wouldn't walk in front of a moving car on the road). I relate hi-viz vests to the current attitude towards road safety. This seems to be wholy orientated around speed. I know of loads of people who don't drive, they operate a vehicle. They have no anticipation, no spatial awareness and a blissful ignorance of what's behind them. Yet they consider themselves "safe" drivers cos they wear a seatbelt and obey the speed limits. Aaaaarrrrgggghhhh.
