In my childhood, when the movie BMX Bandits (1983) [0] was super popular, helmets and any kind of protection did not exist. We did all kinds of crazy stunts, influenced by the movie. I don't recall any harmed kid among tens if not hundreds. Scaped knees and elbows - sure, but that's all!

Please ask Gemini to explain you that you cannot generalize over small samples like your two kids or a few dozen kids from your childhood…

		Literally no kids of a mid-size town in Bulgaria had no head injury riding a bike w/o helmet since I was kid. Not sure where you got the two or a dozen. In fact, a dozen is a fairly good sample size in terms of medical studies, sometimes done with conclusions done with smaller cohorts. In fact, the first COVID-19 booster by Pfizer was only tested on mice, not on a single person even, yet it was administered to billions of people. Helmets and bike gear are in industry and American industries have powerful lobbies.
