Them barriers will definitely be reassessed. Can't see them continuing with them.
They did mention the HANS device a few times during the live race and how it contributed to his survival.
What was extremely well proven was the amount of fire safety rules working to a tee, there has been a temptation to relax some rules as additional ones come in place.
I was not aware of this, and have been watching F1 for a very long time.
What rules did they want to relax?
