@cerealzealot I'm glad you and everyone is ok. I did see the video and yes, you couldn't really avoid it. For those who didn't see, here's my memory of it.
Car traveling behind a pick up of what looks like pretty close. Like a autopilot setting of 3-5(I'm guessing) and the truck sudden cut over to first lane due to a car in front of it looked completely stopped. OP wouldn't have see this. The truck was blocking view and when these situation occurs, you don't have any time.
Did you guys see another accident video from yesterday on reddit how his autopilot suddenly cut over to slower lane to avoid a collision, where the Hyundai behind it (same position as OP in this thread, slams right into the rear of the car in front.)
I was such a young dumb driver for the longest time. But after getting the Tesla, I'm so worry about phantom braking that I try to drive in lanes without many cars in front or behind me.
Wow that video, it's exactly what happened to me (I'm the car crashing, and the Tesla avoiding the stopped car last minute was the pickup in front of me). FSD is incredible.
