A summery of what is or is not happening on bright head lights.
With world trade as it is due to Trump, I would think nothing much will happen.
It appears what is needed is more rigidity in the way headlights are fixed to vehicles (less likely to get out of adjustment) and very effective automatic level control.
The last hospital transport driver I traveled with was complaining about oncoming bright lights, I suggested he looked where we were going and not to look at them they were going the opposite way! A few minuets later he said, "that was a good idea, he was not having problems any more!"
