Well, yes and no. The first development which is more than ten years old at this point, was to have projector xenon lights that are veery bright below a sharp line. That line is supposed to be kept below eye level of oncoming traffic, and there is a sensor that adjusts the line height. In Europe there is also a requirement to have washers on the headlights if you have this. The system kind of works fine, except when it doesn't, for instance when driving over a curved hill where it cannot work due to geometry, or when a sensor fails.

Then in the past 3-4 years, matrix LED lights became popular, where you have an array of LEDs with narrow beam optics that are aimed in a slight spread, so that each LED covers a specific area of the road ahead. Then there is a sensor that detects oncoming traffic, and dims the one or two LEDs that point towards those cars.

On the Model 3 and Y there seems to be a particularly frequent failure mode with the matrix LED where the lights, or sometimes just one of them, doesn't detect oncoming traffic at all. It also occurs when they are driving behind someone.

Couple of weeks ago I was behind such a Tesla at night, and I had to just let him get far in front of me, because he kept getting blinked at with the ultra-powered high beams of every oncoming semi trailer. Of course the poor driver couldn't do a thing about it.
