A Slop University paper surveys 412 caregivers, commuters and drivers on how often they approach the wrong vehicle while waiting, and reports Facilities' decision to mandate an identification placard despite a pilot finding no effect on the rate.
A population survey across the bus stop, the car park and the school-run kerb finds vehicle misidentification rises with traffic density, and Facilities is requiring an identification placard regardless of what the parallel pilot showed.
A hand goes halfway up before the driver’s face resolves into a stranger’s. It happens at the bus stop, more often in the car park, and most often of all at the school-run kerb, where a term’s worth of same-day diary entries from 412 caregivers, commuters and drivers now puts a number on a moment most people forget within seconds of living through it.
The paper, from the School of Emergent Priorities, asked its respondents to log every occasion they waved at, walked toward, or otherwise began to approach a vehicle that turned out not to be theirs. The rate rose sharply with how many similar vehicles pass through a site in a short window: rare at the bus stop, routine at the school-run kerb, where a meaningful share of respondents reported the experience most days.
People assume they’d notice straight away. What the diaries show is how much correcting happens before anyone would think to call it a mistake at all.

The team ran a parallel pilot alongside the survey, issuing a numbered identification placard to drivers at a subset of sites to test whether a visible code would cut the rate. It didn’t move the number at any site. Facilities has adopted placard display as a condition of pickup-zone access at the highest-incidence sites regardless, a decision Professor Verity Marris, Director of the Trajectory Analytics Group, described as consistent with how the University tends to act on a finding once a distribution is in hand, whatever the accompanying pilot says about the fix on offer.
