Hey, really folks, that need of a split folding rear seat-back is WAY overstated. Example:

Me. I have owned about 14 cars since 1979. None of them have had SFRSB.

The one time I needed to carry something large like that in my HCH, I ran it through the rolled down front passenger window into the back rear seat on the driver side. About 2 feet sticking out of the window, not a problem.

People get roof racks, bike carriers, ski carriers, etc. Or borrow a friend's car, or a family member's car.

The only person who should reject a sedan because of lack of a SFRSB is someone who has HAD one, has USED IT FREQUENTLY, and has become spoiled by it.

That's a VERY small portion of the population. I think that's why Honda's Marketing Types decided it was not something the Hybrids needed to become successful.
