It’s not an issue with limitations of current technology. In some cases it’s just greed and laziness. I’ve had two vehicles that have the ability to be more friendly to other drivers, but that functionality is only enabled outside of the U.S. (matrix headlights or the equivalent).

GM vehicles had been notorious for having poorly adjusted headlights from the factory. The fact that Xenon systems seemed to always come with auto leveling and LED often does not is crazy.
