my dad used to ride me around in one of those rear mounted kiddie seats, of course without a helmet on my head..... you'd probably get arrested for doing something like that these days.
They are considered perfectly safe here - safety tests are done - lots of parents haul their kids with those - but with helmets.
It's a little secret you didn't know about us women. We're all closet Visigoths.
