most people dont remember luciano burti. this italian driver suffered a pretty bad crash and a concussion pretty much like massa.
Some more then others
he is Brazilian
Burti has a point though, I personally did think about how the visor did detach one the one side, but didn't know enough about helmets to know weather it was a problem or just visors we not meant ot take that sort of impact.
One thing I didn't know is how Visors had 4 bolt to attach it to the Helmet but now only has two to save weight. That is something that the FIA of the people who regulate helmets should looks at,
also i didnt realize how much damage was done to burtis helmet in that accident at spa, Man he was luckier then i ever realized
