You are the authority that has decided to prioritise this seating for the elderly, pregnant or infirm. Most kids today visually augment their commuting environment.
Who controls the rights to augment this space? By what authority? What mechanisms can you exert to exercise that authority?
Or. Your authority is irrelevant. How do you create the kind of demand pull needed to engage commuters to sufficiently buy into your authority?
Hint. It’s not about the seat.
Technology amplifies behaviours.
