> BMW’s dynamic brake light, for example, flashes during emergency braking to alert trailing drivers, greatly enhancing road safety.
Mind you, that this is not enabled in all countries. In the USA the rear fog lights turn on in addition to the brake lights under heavy braking, as flashing the lights weren't allowed.
They remain on until you no longer depress the brakes.
Unsure if they're allowed right now, or whether the ones you see are aftermarket mods.
For BMW you can change the coding (configuration) relatively easy.
There is also a difference in 3 flashes when you touch the brakes, constant flashing while pressing the brakes, or only flashing under having braking.
I can't imagine driving in stop&go traffic where all brake lights are constantly flashing.
