I love irony!
It's about taking easy precautions to prevent something no matter how unlikely numbers say it might be, do you not get that? Most drivers will never 'need' their seatbelt, most airplane passengers will never need their seatbelt, most police officers will never need their stab / bullet proof vests. Those are all used because in the unlikely and unwanted event of an incident it may just protect them. Why are you arguing against this idea?
We all get that, except it appears you!
It is about taking the easy precaution of wearing a helmet whilst walking to prevent ahead injury no matter what the numbers say it is as likely as it is when riding a bicycle, which you feel is necessary!
Choosing to dismiss the facts and evidence in favour of a personal belief is your decision.
Once again the increased use of helmets is being advocated, yet bizarrely you continually fail to comprehend this.
Pedestrian helmets should surely be worn because in the unlikely and unwanted event of an incident it may just protect them. Why are you arguing against this idea?
No pedestrian feels at risk enough to have to walk around wearing a helmet. Being a pedestrian is, to the average, smart and able-bodied person, very safe and routine. No ped would feel it appropriate to walk around with a cumbersome piece of plastic and foam on their head, I'm fairly sure. Again I reiterate, travelling on a road at anywhere between 0-30 mph alongside cars, this is felt more appropriate by people, apart from you and other non helmet wearers, because of either a) you don't think you'll ever get a head injury b) you don't think a helmet would help in the event of a head injury c) They look stupid.
Once again you are totally wrong about what is being posted.
I don't know how to get across to you in terms that are simple enough for you to understand
1. You have no idea whether any of us wears a helmet
2. It is stated clearly that head injuries occur in both cyclists and pedetrians
3. Helmets work in some cases, but not in others and can have some adverse effects - helmets would be more effective in pedestrian use due to the lower impact speeds. The advocacy is for increased helmet use.
4. Care to point out where anyone has posted that helmets look stupid?
However thank you for this section of your post - it shows the point we are all making so very precisely. Both activities are of equal risk, yet you have been convinced by the propaganda that walking is safe and cycling is dangerous when the risks are in reality similar.
You have simply dismissed the real and equal danger of pedestrian head injury and then in a classic case of denial come up with multiple excuses why.
I've read enough accounts of people on this forum alone who have had offs involving hits to the head, whilst wearing a helmet, to warrant wearing one. It's just not enough of an inconvenience, as a London cyclist, not to wear one IMO. If you haven't already, search back at past discussions and fellow cyclists with near tragic stories about themselves or loved ones who have seen the effectiveness of their helmet first hand. I, like lots of others, am just not willing to brush off those stories in a 'oh but they're in the minority so don't wear one you hypocrite unless you wear one walking down the road!' manner.
What about pedestrians who have had equally tragic losses?
Is the death, injury of a loved one somehow less traumatic, or life changing?
This is something that requires an explanation as to why you feel this is so, after all surely both groups have the same "responsibility" and the decision to wear or not wear is going to have the same effect.
