My misnomer pet peeve is "passive restraints" in cars. These are restraints like airbags and automatically-applied seat belts that actively restrain the occupant. They're called "passive restraints" because, by being active, they allow the occupant to be passive (not having to bother latching the seat belt manually) and still receive the benefit of the restraint.
