I agree, but they have to be able to see you in the first place.
I'm on the road 8 to 10 hours a day as a city P&D driver which given me ample opportunity to observe what works.
I'm not saying high-viz doesn't have any benefit, but you don't need to be seen a long way off, you need to be seen by those in close proximity to you. Many riders I see have lousy roadcraft, riding in blind spots, tailgating, or poor lane positioning that makes visibility enhancements pointless. If they can't
see you, they won't see you.
There's two reasons I prefer lighting, first is it will cast a "light cloud" in poor visibility conditions such as darkness, rain, fog, and snow. Second is the greatest threat is left turners where "directional" lighting is the most effective, and high-viz the least.
Not believing is different than not using.
