You must never drive on a curvy roads then. Every car I driven waits until the approaching car is fully around the corner, blinding them for a full second before dimming, instead recognizing the headlights around the corner and dimming earlier.
It's quite magical and weird to observe in real time. When driving past oncoming cars, you can see a halo of darkness around each car. There are videos on YouTube that show the effect pretty well.
It's not hard to know when a car is approaching from corners / hills; there's light before they get there. I have fun manually adjusting the brights; I drive automatic transmission, lighting is the only fun I get.
