- cresting a hill. Normal people can see the cone of light from the approaching car and often turn classic high beams down before it blinds fellow drivers. These do it only when it detects the actual light source, giving a 0.2-0.5 (about) flash of bright light.
- Wet and snowy ground. Even when they re-align themselves somewhat properly they can be blinding due to reflections which are not part of the angle-calculation algorithm.
- Failure to detect pedestrians and cyclists. Self-evident, but when I am not in a car I am impressed by how blinding it is.
Personally I consider them to decrease safety for everyone except the car with those headlights. I also feel like it is yet another badly designed automation which adds to the ability to slightly doze off and pay a little less attention to traffic.
