My dad's 20yo Citroën had self-leveling lights, which weren't user adjustable (at least not in an obvious way). However, even though the lights were relatively bright (Xenon), nobody ever "complained" about them, they somehow always found a way to not blind oncoming cars while lighting the road very well.

They were fixed pattern, with the high beam on a manual switch, though, so they never tried to guess whether there was someone in the oncoming lane.
