Yeah, when i saw the third seat belt, i was thinking that they might have more to show later ?I like "box", especially clean well proportioned like the first LS and the LS which is to be replaced.
Another point, made about the rear seats: those are three seats, not 2 individual seats that are optional in many cars. Previous/Current LS also has 3 and optional 2 individual seats. Maybe they will yet show the individual seats in the LS500h. It would be nice for next Land Cruiser/LX to also get 2 individual rear seats.
I would also like to remind, that good cars in this class lack folding rear seats. Thanks to a rear "firewall", the cabin is completely isolated, while also reinforcing the whole structure of the unibody. The result is uncompromising comfort. Tesla S can get a way with that (and frameless windows) thanks to BEV silence. But imagine BEV in an LS? That is what I wish the GS would be.
