Nobody had ever angrily flashed their lights at me until the first time I drove a new car with automatic lights. On one occasion blasted someone 50-100' away, which there's no way I've ever done. There's a long dark road I drive on often where every time there's at least one car I can tell left its brights on too long, and it's blinding.

Perhaps you're a better-than-average driver? I unfortunately am not, and have had the opposite experience (people flashing me because I forgot to turn off the high beams, or couldn't do it fast enough due to e.g. a corner, or drinking water with that hand, or whatever). In long straight lines it's relatively easy to do it, on windy roads not so much. On the other hand, with current car I don't remember anybody flashing me.

Personally, I just developed a strategy for dealing with too-bright-incoming-lights: just focus on the right edge of the road - that takes my eyes off the lights, and it's where the danger lies anyway. With that, late-commuting vehicles are a lot less of a nuisance than people who just have poorly tuned low beams or simply keep high beams on always. And those problems/ people are unrelated to the "automatic commute" technology - arguably the tech improves things on that front, even in the not-so-great implementations.
