On seeing a damaged one, it is easy to assume that a serious injury has
been prevented. Cycle helmets split very readily, and often at forces
much lower than those that would lead to serious head injury. Helmets
work by absorbing impact energy through the crushing of an expanded
polystyrene liner. Once compressed the liner stays compressed. It does
not bounce back to its original form like reusable helmets for some
other activities. If a helmet splits before the liner has partially or
fully compressed - and this is often the case - then it has simply
failed. It will not have provided the designed protection and may in
fact have absorbed very little energy at all."

Is cycling especially dangerous? No it isn't.
> A helmet will help in some cases.If we are talking about fatal head injuries  then walking and
travelling by car are more dangerous than cycling, in absolute and
relative terms. Do you insist on them wearing helmets in these
circumstances? I am not picking on you, just asking questions. De's
pages are also a useful read on this issue.
 head injuries where the person would not have died from other
causes anyway. Even a perfect helmet is of no use at all if people die
from other injuries.

You may suffer from "pedestrian inferiority complex".
[for those of you not familar with Effective cycling, cyclist inferiority complex is the term Forester coined to describe the condition of cyclists who believe they must never, ever, impede a motor vehicle]
