Still, from a very cursory bit of reading it seems that these are designed to detect other vehicle headlights only. How about pedestrians and cyclists (or even motorcyclists)? I'm really not convinced that these sorts of technical solutions are the best way to address the problem (in the same way that forward and reverse cameras - while helpful - aren't a proper solution to good old fashioned line of sight).
There's no reason matrix headlights can't block light for any reason, the Teslas and other ADAS systems see bikers and pedestrians so I don't see why that wouldn't be possible.
And I don’t know that they’ve shown this for pedestrians on the pedestrian path, at distance, at night.
It's possible that this awareness is what's used as input for the matrix headlights. Either entirely, or in coordination with detecting oncoming headlights.
I'm confused about your mention of technical solutions. What would a non-technical solution look like?
Something like ensuring that headlights are lower. I'm not against technical improvements, but I think that simple, less error-prone improvements should be given higher priority.
