No, it's not. What you assert as personal choice affects public policy in several ways and thereby impacts the freedom of everyone to ride. I wish you were correct but that doesn't make it so.
I'm coming at this from a different point of view than most. I've spent more days in hospitals, and had more A&E visits due to non cycling head injuries than most will have done due to cycling related head injuries.
I've been advised by neurologists and orthopeadic specialist, that due to the nature & frequency of the fits/siezures/episodes/call them what you want, serious consideration should be given to wearing a helmet as an everyday item. I've one of what I'll call the older style cycling helmets somewhere, too small now as is the body armour I was given to wear. The
reaction to the condition was, and still is, bad enough. I didn't want to bother with all of that either, as a pedestrian. I was asked if I wanted to take part in trials of an inflatable device, that for the most part wouldn't be as visible as ordinary head protection, remember the inflatable helmet that was put on here? But I'm not a fan of wearing much round the neck on a daily basis.
I wear a full face helmet, that covers the sides and the back of the head, with some facial protection when cycling, on two wheels. My choice, despite the looks it gets.
If the specialists in their fields have had to do training to get to the point where they can advise people, what was your training?
Every helmet thread has instances of how injuries might be able to happen, some backed up, some not. The human body isn't concerned with the laws of physics and impact speeds when it hits something, causing it's movement to alter or cease.
I'll throw two actual, non cycling, impacts into the mix. You can argue over the science behind both. Maybe even explain why the outcomes were what they were.
Face plant from a standing position onto a marble floor. No cuts, cracks or bruises.
Fall to the floor from a sitting position onto the steel floor. Three large cuts, over a dozen stichess, broken jaw and two clear cracks to the skull.
In both the normal after effects were felt. So what was causing what to be sore can never be said, impact or condition.
As for the "seriously scrambled" comment made by yourself, have you any idea how offensive that remark is?
My brain, along with that of practically every person, may be far from perfect but it's got me this far.
