In the video (starting at ~13 seconds), the Tesla is at least 16 and probably 20 car lengths from the back of the bus with the bus red flashing lights on the entire time.
If the Tesla can't stop for the bus (not the kid) in 12 car lengths, that's not p-hacking, that's Tesla FSD being both unlawful and obviously unsafe.
