He hit the barrier straight on with the nose. It was quite a big shunt and it´s probably a pretty strong part there due to safety reasons.
Most of the time you hit something head-on it´s a tire barrier absorbing the impact.
Or you hit things at an angle that breaks the car down in a supposed manner due to safety reasons.
It could be that he hit the barrier at the perfect angle at the right speed for the nose to fully be destroyed.
Think of it like this, boil an egg, gently hit it against your head.
It will hurt some but if you do it hard the shell will crack and it won´t hurt at all.
That´s my theory but it´s probably wrong
The truth will come out...
