All of the tints I've mention has a VLT of 5%. Would you still say it's placebo effect?

Before saying it's placebo effect, why don't you try riding on a vehicle that has V-Kool OEM 05 as wraparound tint. From there, doon mo sabihin kung ano ang observation mo. Compare it with similar products from 3M, Lumina, Platinum and SolarGard.
I also know of the observations of users. However, I'm asking why would there be better visibility.

Observations and empirical data are different. It's like the science of audio. You know it's good.. and some are better than others, but why is it better? That's what I seek.

It is dark in a sense that it has a VLT of 5%. However, VLT is measured by the percentage of light from the outside permeating to the inside. There's no "standard" on how to measure light transmission from the inside to the outside so it is wholly possible for the outside to be "clearer" when viewed from the inside. My question now is why and how. Maybe VLR has an effect? Maybe LE? or maybe our visual acuity?
