This hit on a peeve of mine, that automatic high beam systems really suck for pedestrians. Manual control is genuinely better in this regard. Try walking around at night in a wealthy neighborhood, and about 1/8 of the cars just blind every pedestrian.

I assume you're an American? As a Brit, your comment confuses me. Why would anyone ever have high beams on at all in anything reasonably described as a "neighbourhood"? Do built-up areas in the US not reliably have street lighting?

Here in the UK, it is pretty much universally the case that if there are buildings, there are street lights. (Maybe there are occasional exceptions where there's a single building in the middle of nowhere on a rural road; I'm not sure. And I suppose there must be occasional outages of street lighting even in e.g. dense city centres. But such things are rare.) Having high beams on in almost any context where there are buildings around is therefore unnecessary, against the Highway Code, and quite possibly criminal under RVLR reg 27.

I'm not the one you asked, but I think a lot of 'wealthy' neighborhoods in the US mean suburbia with larger single-family-home lots, and roads often feel a bit more rural. In my area in California, these are often unincorporated (county) lands just outside larger towns.

You sometimes see a very clear boundary. The more middle-class housing is subdivisions built all at once somewhere in the 1960s-2000s, with underground utilities and street lights. This infrastructure was mandated by the city, when the developers were looking to get their newly built neighborhood annexed into it. Around the next corner, darker streets with overhead utilities and more spread out lots with oversized "McMansion" houses. These are following the more relaxed county building codes and had the space available for such construction.

These roads are also more likely to have expensive new cars with all the computerized functions. Walking in this limbo world at the edge of our town, I've also noticed being blinded by cars as a pedestrian with more dynamic effects. I suspect are the car's system actively painting me with more light. It is a little bit like the "fringing" you see when the cutoff of older HID projection lamps sweeps over you due to road undulation. But it happens too quickly and both vertically and horizontally. It feels like being hit with a targeted spot light.

I wish the engineers spent the same care to put a dark halo on a pedestrian face as they do for oncoming drivers. Even when carrying my own flashlight, such encounters can be dazzling enough to basically go blind and not be able to see the dark paving in front of me for a minute. My light is more to make me visible to the cars than to really illuminate my path for myself. It doesn't stand a chance against the huge dynamic range of these car lighting systems.

Yes, exactly, very well explained.

I'm pretty sure pedestrians would rather blink a few times than get run over.

This is a big reason why "high-beams as default" is not the right choice
