How about just banning super bright blue spectrum, as opposed to old style yellow lights? Those super brights on low beam are worse for oncoming drivers than old lights on high beam.
Automatic dimmers take aware situational awareness and responsiveness, and they still don’t keep high beams out out of pedestrians’ faces.
And they’re expensive. More failure points. And hackable. Will there be a “smart” light exemption for old style lights?
The headlamps, whether incandescent or LED would not be the "point of hack". That would be the control computer, but only if it were on a wireless network of some sort.
