The only fashion accessory legally required to survive being wrong about your reflexes.

means A protective helmet worn by motorcyclists to shield the head from injury in a crash.

from A straightforward compound of two borrowed parts. 'Motor' comes from Latin 'motor,' meaning 'mover' (from 'movere,' to move), while 'cycle' traces to Greek 'kyklos,' a circle or wheel — together naming the wheeled, engine-driven machine that emerged in the late 19th century. 'Helmet' is older and homelier: a diminutive of Middle English 'helm,' protective headgear, kin to Old English 'helm' and Germanic words meaning 'to cover or conceal' — the same protective instinct that names the 'helm' you steer a ship by. So the word literally stitches a moving wheel to a covered head.
