I take on board what you've said. It's like walking through treacle having a discussion online..lol. but..I envisaged the lady's scooter being hit, she falls to the ground, striking her head on the roadway or kerb edge..not a car hitting her head.
I'm surprised at those stats re a drop in cycling and more head injuries amongst cyclists. What country, where there is compulsion, shows those numbers ?
Here are the findings from the Cochrane Database of Systematic Reviews,
Data from hospitals show 40% of cyclists and 45% of child cyclists suffer head injuries. Three quarters of cyclist fatalities have major head injuries. Meanwhile, a Cochrane review suggested helmets reduced the risk of injury to the head and the brain by a substantial 65%-88%; and the upper and mid-face by 65%.
However, Cycling UK say this:
"There is in any case a good deal of controversy about the effectiveness of helmets. As mentioned, they are (and can only be) designed for minor knocks and bumps, not collisions with fast cars or lorries. There is also evidence to suggest that: some cyclists ride less cautiously when wearing them; that drivers leave less space when overtaking helmeted cyclists than those without; that helmeted cyclists suffer 14% more collisions per mile travelled than non-wearers; and that helmets may increase the risk of neck injuries. It is therefore entirely possible that helmet-wearing might have a net disbenefit even in safety terms (a point also suggested by some of the empirical evidence), not to mention the health and other disbenefits identified above"
Quite a debate,really but if I had a bike I'd wear a helmet.
