 Well, since the helmet certification standard was established
(essentially less than 300gs linear deceleration in a 14 mph impact), it
became known that linear deceleration was far less of a problem than
rotational acceleration. Twisting the head and brain caused far more
brain injury than smacking them. But a helmet protrudes at least an inch
from the head, providing a longer lever arm for glancing blows,
potentially worsening rotational acceleration.

  People who ride fast and wear helmets are more likely to fall and be hurt. People who ride to the grocery store and home like you are not. Your comments ae usual are complete nonsense.

So does that mean that Miguel Indurain should have always worn a helmet? And Greg LeMond? Bernard Hinault? Eddy Merckx? Jacques Anquetil? Fausto Coppi?
