Spatial Sovereignty and the Unpriced Transit Commons

SLOP2950 · Week 6 · Subway / Bus

None of them are against any rule. All of them cost someone else something.

The standard moves

None of these break a written rule. All of them cost another passenger something. Slop University’s Centre for Transit Ethics classifies each as a distinct mode of informal spatial requisition — jurisdiction claimed by posture rather than by any instrument a passenger could point to.

  • the bag on the empty seat — a claim on space nobody is sitting in
  • the wide pole grip — a hand and forearm doing the work of a whole handhold
  • the pitched-up headphones — volume set to be heard, not merely audible

Three people stand in the aisle holding the rail; the seat beside a seated passenger stays full of a bag that could sit on a lap instead.

This is a genuinely unresolved one: some transit authorities treat wide sitting as simple entitlement and have run campaigns naming it directly; others point out that seat and pelvis geometry differ enough between bodies that “spreading” isn’t always a deliberate claim on extra space — the debate between intent and anatomy runs through most transit-etiquette arguments about this exact posture.

An unpriced commons

There’s more space in a carriage than any timetable accounts for, and no mechanism except posture decides who gets how much of it. This is, at bottom, an unpriced commons in the fullest economic sense — a resource with no owner, no meter, and no enforcement body except the mutual embarrassment of the passengers standing in it.

Bad manner vs. good manner

🟥 Bad manner — Non-Consensual Spatial Requisition (NCSR): On a crowded evening bus, a passenger stretches both legs across the empty seat beside them and keeps a bag on the seat rather than their lap, while three people standing in the aisle hold the rail and say nothing. Slop University’s Centre for Transit Ethics classifies this as a requisition rather than a mere sprawl: the seat is annexed without consultation, and the surrounding population absorbs the cost in silence, which the Centre notes is not the same thing as consent.

🟩 Good manner — Voluntary Spatial Yielding Protocol (VSYP): That same passenger pulling their legs in and moving the bag to their lap or the floor the moment the bus starts to fill — a unilateral de-annexation, completed before anyone has to file a claim. The Centre catalogues this under “pre-emptive commons management”: a resource returned before scarcity even has the chance to make the case for it.
