If the world is reflected in a mirror which switches the left and right side of the car, the " reflection " of this angular momentum " vector " ( viewed as an ordinary vector ) points to the right, but the actual angular momentum vector of the wheel still points to the left, corresponding to the extra minus sign in the reflection of a pseudovector.
