I say unusual in the sense of Japan seems to be the only one to have solved the issue of how do you transport 2 kids on a bike not with "big box" like the dutch and subsequently the entire western world but via 2 seats, they're apparently very popular over there as a means of transportation.
You mean that that's not the world you're in. There are plenty of countries where literally all of these things are the norm, and your experiences are a rare exception.
I don't think that helmets are bad or unnecessary, but I do agree that they are entirely ineffective against the things Americans will trot out the "should have worn a helmet smh" victim blaming for, i.e. getting punted by a speeding F150.
