Ok, from what has been shown (shined?), the Germans have the regulations that require a "no glare" for oncoming traffic. Maybe its more than just "no glare", but that seems to be a very big difference. As far as beam spread and brightness (lumens or lux), I would imagine the manufacturers in the States have it just as good or close to it.
It would seem to me that the optics for the top horizontal cut-off can be done here in the States. It isn't but that would be something all the manufacturers can add to their "new and improved" models for next year. Is that too difficult?
