I think people's expectations is the primary reason why cars today generally don't have bench front seats. A lot (perhaps the majority) of big SUV's today are being sold to consumers with bucket front seats and massive center consoles in lieu of bench seats; I can imagine it would be even less popular in a smaller vehicle such as a Leaf. For that matter many minivans are being optioned with "Captains Chairs" second row seating in lieu of a 3 person bench.
