The USA has a rather busier GA environment than the UK but does so without a need for hi-viz jackets. I quite happily wander to & from my aircraft on the GA part of very busy airports such as Atlanta Intl, Miami Intl, Tampa Intl, etc etc ad nauseum as well as numerous smaller fields without have to wear a hi-viz. To follow the logic of those who mandate the wearing of such things the US should have a worse safety rate than the UK. Has anyone *any* information that supports this assumption?
