In my opinion, According to the Eastern States Laws.
This is Pure and Utter Bullshit.
However, In your state Carbon Fibre bonnets, Maybe legal.
However the Bottom line is..
All bonnets must meet ADR standards, This means All bonnets must Crumple on Impact.
A carbon Fibre bonnet does not, It splits and Shatters.
Therefore Rending the Bonnet Not Legal.
The Smarter thing to do will be to contact the correct authorities, to check if mine or 'This Spolier Guy's" comments are correct.
Thanks,
