You are thinking about the Ebay Chinese LED light bars that people put on their "off-road" vehicles. The problem isn't with the brightness it is with how they are aimed. If you turn on stock HID headlights and point them at a wall you will notice the bright bit is a region of the wall from the ground to about a meter up. Then there is not very bright light diffusely showing higher that is used to illuminate road signs.
High beam lights and aftermarket lights are not aimed like this and thus shine into your passenger compartment. Properly aimed lights never point in. An issue in the USA is that unlike Europe we have no requirement to autolevel lights even when cresting a hill. So you notice that when someone comes up over a hill you get flashed with light. That might be an issue with these.

By that definition, properly aimed lights haven't been invented yet. I have headlights like that, where you see brightness end at a horizontal line. Going over the crest of a hill angles the beams in a way that goes into cars. Actually my family has two cars. I get a lot more people blinking their brights at me in the one with that kind of headlight, presumably because they think my brights are on when they aren't. The article describes automated systems to turn the laser version away from detected cars ahead, so it will just blind cyclists and pedestrians.
