Re: HEY!

Because a higher standard always includes the lower standard and Federal Bureaucrats always have their heads fully implanted where the sun don't shine.

It's simple physics. Some of the DOT helmets with a softer lining absorb impact better at lower speed than the Snells. At racing speeds those DOT helmts could allow the skull to crush up against the helmet's outer shell while the Snell's stiffer lining would protect the brain enough for it to survive in a tank.

The point was that there was not necessarily any advantage to wearing a Snell helmet if you kept your speeds below 100 mph.

The AMA does not report any findings because they are spending your dues trying to overturn helmet legislation everywhere they see it. Any findings that helmets save lives on the street would therefore put them in rather a sticky wicket. The track is a different story, largely because the AMA (ever the legally aware) don't want the liability of unhelmeted racers.

Re: While we're on the topic

Snell accept only full-face helmets. Period. No swing-up helmet made is even considered for testing by Snell, because they think that the hinge on the "jaw" portion cannot be considered structural, therfore making the helmet really a 3/4 helmet, adn tehrfore automatically not Snell-compliant, so they don't bother.

As a clarification, the Hurt report apparently found that in 90+ percent of all head impacts, first contact with the ground (not necessarily the first contact, just the first contact with the ground) happened in two places: on the chinbar, just to the left of center, and just to the right of center. It's not hard to imagine a "hinge" roughly at ear-level being torqued off by such an impact.

I agree with you even as an AMA member!

They serve other good roles, but helmet policy is not one of them.

I guess you allready had your crash ehhhhh?

Or you are smokingU something very, very, good!
