They dissagree with your theory in almost all respects.

We are very familiar with "them," although you don't seem to realize
that "they" are Randy Swart, a single person who since about 1975 or so
has devoted his life to the dangerization of bicycling and the promotion
of mandatory bike helmets. That's for everyone, including adults.

Swart copies and publishes every bit of pro-helmet nonsense he can find.
For decades, he was one of the loudest trumpeters of the purported
"85% benefit" from the 1979 Thompson & Rivara "case-control" study.

Sorry, typo. That was 1989. But its "85%" is still uncorroborated 28
years later.
