While I agree that going that fast minimizes or negates the saftey of the helmet, your hour-record link is useless here. While cycling on a flat surface, I easily club up to 30 mph (for a stint). On a downhill, I've had to use my breaks to stay below 40 mph. The parent post did not say she was sustaining that speed for a whole hour, plus this was downhill. Despite how fast she was going, she should have been going slower and riding defensively.
