I guess I’m just especially confused because “regulatory capture” suggests there are regulations, but as the commenter above points out, there are relatively few. That’s why cars and trucks can have brighter headlights that aren’t well aligned: nothing stops them.
It's another example of regulatory capture where owners of pickups and large SUVs have free rein to dazzle lower folk.
Interestingly lights on heavy trucks are regulated in height and aim so that they don't dazzle other drivers.
