We discovered, after accidentally having twins and bumping the kids count to 3, a typical sedan cannot physically carry more than two children because you cannot fit 3 or more child seats in the back as required by law. That's why families of 3 or more kids have minivans. It's not like the 80s where you toss the kids in a station wagon and let them wander in the back, they are required to be in massive padded seats.

Chicco infant and EvenFlo little and big boosters will get you to three in a back row. Use a seatbelt extender or two to make buckling easier. Not taking away from your point, because parents absolutely prefer two to a row, just helping anyone who happens to read this.

Families of 3 also have e.g. station wagons. Big sedan should be fine seating-wise too.
