But were not advocating that pedestrians should wear head protection, and of course they have a 50% greater chance of serious injury, there are more pedestrians (compared to cyclists) , and they regularly swap between pedestrian and vehicle routes . And they're more likely to be distracted by other things, such as phones, friends, shop displays etc. , not to mention the vehicle drivers who are equally distracted and not paying attention to whats going on around them.
I didn't reply to the OP, I replied to your unequivocal statement:
Now would you explain why a pedestrian head injury is somehow less traumatic, devastating or more acceptable to the level where they shouldn't be prevented?
Doesn't answer the question.......
There is also the issue that cycle head injuries are not common. Cohort studies of hospital admissions show them to be a very small minority.
