maximum height allowance on vehicle’s headlights so that they’re not right in a sedan’s driver’s rearview mirror when a pickup is tailgating
That's actually already legally mandated at least in states that require state inspections. Headlight angle is supposed to be one of the things you have to check in order to pass inspection.
In practice, mostly nobody checks it and it doesn't matter. But it should.
Not just the angle tho, the height of the headlights themselves! Even if aligned properly if the headlights are 5' off the ground and my back window is 3.5' when they tailgate it illuminate the inside of my car !
