The front seats of the Zeppelin swivel 180° (when the vehicle isn't in motion, or that's the plan), so that the occupants can interact with one another as if they were in a living room instead.
Supposedly the glamor of air travel inspired both the curvy, crazy exterior and the more personal interior thus the Zeppelin. I don't want to sound like a downer, but when I think of flying on a plane lately, I don't think of having space to stretch my legs or wanting to talk to the folks around me. Still, pretty car.
