it's mostly relevant in the sense of highlighting retroreflectors
IIHS's rationale document (page 4) states that the intended target of illumination is low-contrast objects, not retroreflective objects.
I personally rarely drive in places where I have 70+ meters of unlighted space in front of me
I personally drive in such conditions regularly. Two weeks ago, I only narrowly avoided hitting a deer that was calmly standing in the middle of a three-lane, nominally-50-mi/h (actually-60-mi/h) highway, which is what prompted me to investigate this topic in the first place.
White people's homeland is not America
For how many years must a people inhabit a location before that location counts as that people's "homeland"? I'm thinking that a timespan of 200 years sounds quite reasonable. Even 100 years or 50 years could be argued for.
Why are you driving with your brights on?
It is mentioned in the IIHS article linked above that high beams are supposed to be used on roads with hardly any traffic.
Researchers from IIHS and the University of Michigan Transportation Research Institute found that drivers in and around Ann Arbor, Mich., didn’t use their high beams enough. Only 18% of drivers who were isolated enough to make use of their high beams did so.
you can't buy a non-lifted hatchback
*laughs in Mitsubishi Mirage*
But, seriously, there are tons of non-lifted hatchbacks on the market.
TIL: According to IIHS (the Insurance Institute for Highway Safety), the stock headlights on many cars are inadequate. For example, the popular Honda Fit hatchback has headlights that are only "marginal" (2 stars out of 4) or "poor" (1 star), depending on trim. (Several different measurements go into the overall rating. Speaking very roughly, though, IIHS wants to see illumination of 5 lux out to a distance of 100 meters, while the Fit's headlights achieved that illumination only out to 72.4 meters.)
Headlight bulbs that are much brighter than stock while still remaining in compliance with laws regarding off-center glare (unlike some LEDs) are available for a few dollars from various sources—e. g., RockAuto. Note that illumination distance increases with the square root of brightness: 1 lux of illumination is 1 lumen of brightness per meter squared. For example, multiplying brightness by 2.3 will multiply illumination distance by only 1.5—but that's enough to bring the Fit up to IIHS's standards (from 72.4 meters to 110 meters).
