I think that was my first point, which you snipped. Not that I agree
that helmet effectiveness is under-estimated.

No one reports head impact crashes where there is no injury. As Jay
pointed out, there are a lot of crashes where a helmet completely
prevents lacerations, and those don't result in an ER visit.

There are also no reports when a wooly hat prevents a laceration. Guy
Chapman's experience, when he was "saved" by his wooly hat, is in no
database.

The wooly hat manufacturers should learn from the helmet manufacturers.
Think of the marketing possibilities!
