And you falsely claimed motor vehicles did not have red lights on the side, but then try to squirm away when shown to be wrong.
Claiming that they don't have red lights and reflective red material on the sides. Red - rear. White - front. Yellow - sides.
Yes, a little red can be seen from the sides, but that's an analogy to claiming that trousers cover a man's stomach. They do by a small degree, but I'd say that shirt covers the torso, trousers cover legs.
