Because the US is very archaic in their headlight standards / rules. I didnt even watch the video, but assume it is similar to what has been available on BMW / Audi / Porsche for quite some time, with some form of tunneling, etc.
If I remember,
@UncertainTimes also has BMW ownership history like I do, so is fully aware that BMWs have done "fancy lights" for years (more than a decade, at least), with all sorts of cool features like automatically creating a tunnel around the car in front of you, changing the shape of the light to not blind the oncoming car, etc.
Never allowed on US BMWs, even if you bought all the appropriate packages. You had to basically access the cars "computer registry" and "hack" turn it on if you wanted to use those features, even if you bought them, in the US.
Thats likely why
@UncertainTimes says that. Until the US government changes the headlight rules, none of that stuff will be enabled in the US, and they havent been in any hurry to do so (as I said, fancy lights have been available for more than a decade, from other manufacturers, and no changes so far to rules.)
