I'm afraid the flashing brake light will fall victim to tragedy of the commons. It's a great idea, but when everyone has it, it just becomes a sea of blinking lights and harder to differentiate. I already hate being behind one vehicle that has it, because it's distracting and I'm interpreting the first time it dims as they're letting off the brake. It's also probably illegal if the law says brake light must be illuminated when the brake pedal is pressed.
