How long before LED headlights can simply shine around the deer (thus not blinding them), as they do for oncoming vehicles. On second thought that would mean the driver doesn't see the deer; maybe not the best idea!

Do those actually work? How widely are they deployed? Newer LED headlights seem particularly blinding to me as a driver on the other side.

Becoming common on most VAG cars for example, even Skoda (their budget-ish brand) - see the video here https://www.skoda-storyboard.com/en/press-kits/skoda-superb-....

I think they're pretty effective; they cut out the light beam exactly where the other car is. There might still be reflections from other surfaces though.

They work but not in the US, where they are illegal (the HW is capable of "anti-daze" but SW is locked out for the US cars).
