LED headlight functionality we don't have, why?

[Hockenheim]

This is direct from audi.co.uk, why don't US cars have these features? can they be enabled?

LED headlights provide for optimised road illumination similar to the effect achieved by daylight.
LED technology provides lower energy consumption and enhanced contrast with a colour similar to daylight, for increased safety and good recognition by other road users. Includes all-weather light function to reduce the risk of the driver being dazzled when visibility is poor (in fog, rain or snow), turning light function which is activated when indicator is switched on (up to speeds of 45mph), and an additional motorway light which automatically increases headlight range at speeds above approximately 68mph. Also includes high-beam assist which automatically adjusts headlights from high-beam to dipped-beam when another vehicle is approaching or when other ambient lighting is detected (i.e. street lights) by a camera on the interior mirror

The only feature out of those that I am aware our US cars don't have is the high-beam assist.

My BMW had the auto dim feature so it is available in the US. My RS7 has no bulbs it is all LED headlights and tail lights and I live in the US. You can't get laser headlights in the US right now.
