I think this accident could've been entirely avoided had the small pink hatchback been a Tesla.
My read on what happened here is that the pink car was making a passing maneuver, and just as the pink car driver checked their right-side mirror/blind-spot and hit the right turn signal to get out of the passing lane, the car ahead abruptly stopped. That explains why the pink car drifted so slowly to the right - it wasn't an avoidance maneuver, it was a simple lane change while unaware of the stopped car ahead. Presumably an autopilot in the pink car would've been able to see the stopped traffic ahead and hit the brakes even while the driver was looking to the right to change lanes.
