Good! I'm constantly getting flashed by smart headlights and auto-leveling systems that simply don't work well. I wish we could go back to simple lights that work and don't constantly flash me every time another driver hits a bump or their smart algorithms screw up.
When the car hits a bump, or crests a hill, then "downwards" becomes pointed directly at oncoming traffic. If anything, quick-reacting "smart" lights would be more helpful here.
Generally, when people like you complain about this stuff, what you're really asking for is for everyone to go back to extremely low-output headlights where you couldn't see almost anything at night. I don't see how that's an improvement.
Those "smart" headlights definitely do not react correctly/fast enough to prevent blinding someone when they drive over a bump or crest a hill- which are things that are almost guaranteed to happen multiple times whenever someone goes driving. Adding the current level of smarts to a headlight does not fix the issue with brightness.
I think we've reached (or are very near) the point where a brighter headlight won't give you as much additional safety as they degrade the safety of oncoming traffic. It's cool for me to have lights that are brighter than the sun, but if oncoming traffic is blinded and hits something- maybe not me, they could be blind for several seconds after I've passed them and they hit a deer or something- then the overall effect is that my brighter headlights made the roads less safe. I have no personal incentive to get dimmer lights, but society as a whole has an incentive to find the sweet spot where lights are bright enough to drive at night and not endanger other people.
"Well, it's not supposed to do that..."
You don't say!
These systems are most prevalent on expensive European brands that have terrible reliability ratings.
Totally obvious when you see which cars are blinding you too usually.
