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.
