Not guilty!

The paper shows that if a car stops at a stop sign, an observer, e.g., a police officer, located at a certain
distance perpendicular to the car trajectory, must have an illusion that the car does not stop, if the
following three conditions are satis ed: (1) the observer measures not the linear but angular speed
of the car; (2) the car decelerates and subsequently accelerates relatively fast; and (3) there is a
short-time obstruction of the observer's view of the car by an external object, e.g., another car, at
the moment when both cars are near the stop sign.
