I was behind two cars on the freeway, one in lane 1 and one in lane 3. They both decided to merge into the center lane at the same time. I remember the sound distinctly because it was so different than I expected. It sounded like two large, empty cardboard boxes hitting each other. No screeching tires or glass breaking sound (both windshields and side windows broke, but remained intact). It was very unexciting.
Fear is a key driver (period). I just heard this on the radio. They analyzed what pulls people in and it’s fear. Fear also keeps people lingering longer. I didn’t hear enough to explain it (I got to my destination before the show was over). Putting it together with other things I’ve heard, the algorithms that are tuned to keep people engaged on the site skill natually choose things that stoke fear and that is probably the same thing that the facist propaganda is promoting, too.
