> You have to stare at the light for a couple of seconds to confirm the light is blinking because the person is signalling, and not because they tapped their brakes and you only saw a change. I've been driving a long time, and this hasn't ever been a problem in my experience. If someone taps the brakes, both lights come on. So the only time there is ambiguity is when a brake light is burned out. Not especially common now that everyone has been switching to LEDs. And if it takes a couple seconds to blink, something is very wrong with the car.
