You mean to say "automatic high beams on Teslas". The ones on our Hyundai Ioniq work just fine, and have never blinded anyone. But in Redmond, WA, Teslas are everywhere and 90% if you're getting beamed, it's a Tesla. Their headlights are, in many cases, improperly aimed out of the factory and their shit auto high beams only make it worse.
I think what you're really experiencing is default/shit calibration from factory (0/"highest it can get") + super-bright LED lights. The first 2 months I drove my M3 everyone was flashing me on the highway, and it took me a while to put that together and notice that it was me with low beams. I realized how bright the LED lights are the moment I saw the orange turn light brighten up a 5m overhead sign from 25m away, and then looked for calibration settings of the beams. Haven't been flashed since :)
There's also the issue where most people who use them clearly think they're fine, or they would stop.
