       Car headlights are way too bright these days.  Seriously hazardous on a rainy night.(Maybe it's just me?)

       @timbray It's not you. You can output brightness from a small area, almost a point source, or the same amount of light from a larger area.The former is blinding, the latter less so.https://www.nature.com/articles/s41598-023-30658-0https://pmc.ncbi.nlm.nih.gov/articles/PMC9508687Very modern cars have dynamic headlights. These are composite LED lights, so an array of point sources, that can be controlled by the cars' camera. The car will darken a segment in which it spots another light source, i.e. the headlights of an oncoming car.As a pedestrian, unlighted, you do not register, so it won't.Most cars do not yet have integrated systems, so registered obstacles from a cars lidar system will usually not (yet) be taken into account.

       @isotoppThey have really shitty patterns. I used to buy Cibie Z-beams, they were very bright but had an extremely sharp cutoff below horizontal and biased to the right ( US). Expensive (once, long ago) but totally worth it. Just H2 bulbs or whatever they were but really well designed reflectors.   @timbray

       @tomjennings @timbray I have a Euro background, regulatory constraints here are a bit different, and somewhat more constrained. A lot of what is street legal on US and Canadian roads would not be here.But yes, a lot of the more modern tech (the things that are part of GSR2, https://www.rac.co.uk/drive/advice/road-safety/what-is-gsr2-important-eu-car-safety-features-explained/m and a few other things that come from an insurance and not a primary regulatory background) is forced on the market through regulation, and is basically too immature to reliably help drivers or innocent bystanders.
