AEB is enabled even when FSD is off, which sounds like the L2 ADAS behaviour you're describing. Just because FSD disengages, it doesn't mean that no other Collision Avoidance Assist features are operating.

> because FSD deactivated itself 4 seconds before impact

This isn't accurate. The driver deactivated FSD 4 seconds before impact. Don't get me wrong, the video looks pretty much like FSD wouldn't have been able to do anything better than the driver did, but she didn't give it a chance.
