High-beam assist with matrix headlights is amazing - keeps the high-beam on but just changes the shape to avoid the exact area that would dazzle someone else.
I think matrix LED lights are not allowed in US? But yes - having matrix headlights is a huge safety benefit. I am driving on high beam most of the time and only small parts are dimmed if there is a car in that sector. Works really well and it was well worth the money (Audi A6).
Just say it's in beta, then you can apparently do whatever you want in the US!
Just got the regulatory framework in place for it IIRC.
