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.

The airbags are actively detrimental to most children to the point where you're advised to turn them off lest they seriously injure them in a crash. Every car manual since the 1980s has points about this in it. They don't work for children because they're not designed for children. Do you not understand this?
No, I always wear one.
