Thanks for starting the discussion on this, it's such an interesting feature, technologically and safety wise.
I recently found a
different video illustrating
adaptive headlights quite well, in fact, I was able to really appreciate it with this one, hopefully this is a good reference for other members too.
Funny thing, I still don't know if I have this on my car, apparently according BMWVIN I do so, I need to remember to check this out.
