The Twitter thread is lacking in attributions, but I saw most of these some months back after a post about scary FSD behavior. I watched with morbid curiosity, and a rising level of anger.
The guy with the white ball cap repeatedly attempted a left turn across two lanes of fast-moving traffic, with a drone providing overhead views. He seemed smart, aware, and even a bit conservative in intervening. Nonetheless, I couldn't help but thinking that none of the oncoming vehicles consented to the experiments racking up YouTube views. If he doesn't jump on the brakes at the right time, he potentially causes a head-on collision with a good chance of fatalities.
Yes, I do agree that beta drivers should get extra training. However, I'm not sure I agree with the premise of beta testing an aluminum rocket on wheels on public roads in the first place.
