I wear a Sam Browne hi-viz belt, relying on this to trigger memories in older people and nostalgia-fake-memories in the young from watching old shows, and make people go "Eeeek! Cop!" But a friend was puzzled some months ago when on a trip to his son's or daughter's sports field he was close-passed dangerously several times; on the way back, holding the hurley that had been left behind (for Americans, hurling is a traditional Irish game that combines hockey and psychopathy), drivers were meekly mannerly.
