Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

Many people cite different reasons, for some people undoubtedly fashion is the reason, other reasons may be :

comfort,
convenience,
** studies showing worse behavior of driver towards cyclist wearing helmets,**
believe that while a helmet may offer some protection in some accidents the chances are very small, i.e the same reason people don't wear a helmet walking or running.
freedom

the bold part fucking pissed me off so much, I end up riding without a helmet and the behaviour of certain drivers are noticeable wary of me, but not enough, so I went one step further and got a decent 2nd hand messenger bag, paint "DEAF" in large helvetica, and bingo.

work better than fucking helmet.

another thing work better is the number of cyclists; the more cyclists on a road, the safer it is (i.e. vehicle drivers are actually more aware of cyclists when they pass some every couple of second).
