I don't think any manufacturer puts in passenger seatbelts based on safety or who might want to ride where.
I bet the decision making process goes like this:
(1) How many seat belts for we HAVE to install
(2) Where is the easiest/cheapest place to put them?
End of story.
It's a sad reflection on the industry that they will sell a family bunkhouse model C without any real provision for kids, carseats, or safety.
I can save them the focus group costs - putting all of the seatbelts next to each other and at the same table is a BAD IDEA! Spread them out so the kids are spread out. Parents will thank you.
