While that video shows control of the matrix (spelling out Tesla in the lighting), that's not the issue. Controlling the light output is easy, It's the detection of when and where to reduce or turn off the light output that I'm convinced that Tesla can't do -- because they can't do it right now with regular headlights. Current Auto High Beam doesn't turn the lights to low beam until an oncoming car is far too close, and doesn't turn them off at all when following another car. It's because Tesla has ongoing, prominent, and obvious issues with consistently detecting things from the cameras. Their "vision" software simply doesn't work.
