You're mistaken
Whereas, now, if I use auto my car will maintain high beam until it has clear sight of the oncoming car's headlights (its probably better than that, but not always). There are cases where it may fail to detect at all - e.g. dual carriage with a good solid central barrier - where it will engage high beam, that won't upset oncoming cars, but truck drivers, sitting up high, will be blinded (and their headlights will not be visible behind a good solid central reservation barrier)
The biggest failing of these silly systems is that they don't spot cars waiting in side turnings. I remember years ago driving a Volvo with matrix lamps along the A414 and seeing the driver of a car in an adjoining left side road giving me his unwavering mid digit as I went past not knowing how to dip the beam.
