There are 6 other cars that crashed, each into the one infront of it, it looks like nobody was paying attention.

If the Tesla was at the back or the middle I think it's highly likely it would have outperformed the other drivers and stopped faster or kept a safe distance.

A series of problems lead to this accident, FSD Beta gets 5% of the blame here for stopping on the highway, which isn't an exclusive feature to Tesla - cars stop on roads all the time.

What this demonstrates is 7/8 or 8/8 drivers here were driving unsafely.
