There is no final report, as that will take weeks.
The rear of the car sheared off when the front hit, not the halo. The halo then wedged itself in the barrier, but if it had more than a little speed left at that point it would have just gone completely through it and a ways through the other side.
"The International Automobile Federation (FIA) expected its investigation to take six to eight weeks."
And anyone could see that the survival cell went THROUGH the barrier, just not very far.A little of the barrier may have been above his head when he was trying to exit, but he was on the other side of the barrier, which is why he had to hop over it to get to safety.
Had he been lodged in the barrier, he'd have probably died. Had the car been without a halo, he'd have probably died.
