From: The illusion of absence: how a common feature of magic shows can explain a class of road accidents
(Left) The narrow signpost in the middle can hide a motorcycle approaching the intersection over a long stretch (150 m, see Haakenstad, 2015) from the point of view of a driver halting at the entry to the main road. In this photo, a large truck is almost completely covered. This probably happened during a fatal accident at this intersection (Amundsen et al., 2015). Based on the findings of Øhrn et al. (2019), one may speculate that narrow obstructions of view like this signpost are particularly prone to evoking the illusion of absence, and thus a compelling, but potentially misleading conviction that it is safe to enter the main road. (Right) The signpost has later been removed. The photo on the left was taken by Pål Bjerke, Norwegian Public Roads Administration and is reprinted with permission
