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.
