There are several cars I cannot find the turn signals on when I am facing them in traffic during the day, and one of those is the Toyota Prius. The others are Kias and a couple other brands. These slits of light that are always on as headlights and then the directional light is another slit parallel to the always on slit of light, and I am looking trying to find the blinker that isn't really blinking as much as it is pulsing - man what horrible design.
