Wearing helmets all the time increases the incorrect perception that cycling is dangerous and discourages people from cycling.
Really, I mean really?? I dont think so I think a lot of people who rode as kids dont see the need now and another majority of people who MTB think actually this is a good idea. Not I'm wearing a lid threrefore I am protected in all situtations.
I agree with your a lid is not a fix for all situtations POV mate but I think you are playing down the benifits (sp) quite a bit more than is true and on balence they are worth wearing. I would also agrue that to be at risk of rotational injuries you need to be still alive and the lid will help towards that.
Either way no issues with you not wearing one mate :D
