SMIDSY
SMIDSY (複数形 SMIDSYs)
The acronym is used by motorcyclists and cyclists in reference to traffic collisions in which the driver of a car or larger vehicle claims not to have noticed a two-wheel biker. It is usually derogatory, in that the claim is often that the driver was not at fault (when they patently were).
A related usage by the UK government is LBFTS (“looked but failed to see”).[1]
