yes, john is inaccurately ascribing the 'do something stupid' admonishment to the bicyclist education materials of the day.

john is manufacturing that, to discredit bicycling education efforts that preceded HIS crackpot education materials.

jon is the sole fabricator of the 'taught to ride stupid' myth in his disengenous fallacies he uses to support his flawed sophistry.

anyone seen that 1963 bikesafety movie "someone got fat?" no 'stupid' message there at all!
