One question I'm curious about is whether or not we will shift to having seats in a different configuration such as having people sit facing each other. Furthermore I'm curious what factors will contribute to one configuration over another. factors that may matter: (1) safety (2) situational interaction (meeting, road trip with family) (3) social norms (what are we used to. e.g. the french sit next to each other in cafes, but americans sit across from each other) (4) motion sickness (5) ???
