Headlights with adaptive-driving beam coming

Adaptive-driving beams are used in Europe, Japan and other markets but are prohibited in the U.S. because federal rules require distinct high and low-beam patterns. As currently written, FMVSS 108 doesn’t allow for a headlight system that dynamically adjusts to simultaneously meet portions of the low-beam and high-beam requirements. To me this is just another example of how the U.S. is behind the rest of the world in many safety aspects, including not requiring all vehicles to have at least daytime running lights.
