I just consciously tried out the Tesla adaptive headlights last night, and it's pretty remarkable IMO. I've had it for a couple weeks with the Spring update, but hadn't driven much at night, and wasn't paying attention. Available on most, not all, Teslas with matrix headlights.
I understand MB and undoubtedly some other make/model cars have had this before Tesla, but new to me.
Maybe TMI but if you can't readily see it blocking pixels at cars you're following and oncoming cars, here's something to look for to make it even more obvious. Approaching a curve right, you can see brights on trees/buildings or other objects left of the road. If there's an oncoming car, once the car starts to get into your cone of light ahead, you will notice the lights dim noticeably on objects in the background. Once the oncoming car passes, brights restored on objects in the background. It's pretty cool, FWIW.
