Great video! I think the brake lights should activate based on g-forces nowadays. For example, always lit brakelight when deceleration is 0.1 g or more, or the speed is less than 3 km/h. Measuring deceleration is better than monitoring pedal input because it will lit the brake lights correctly in case of failures, too. Say the wheel bearing goes bad and the car rapidly slows down: brake light automatically lits if the deceleration is rapid enough. And I truly meant that the limit should be 0.1 g. It's better to lit the brake light a bit too soon than too late and 0.1 g is already far enough from stable movement that it shouldn't happen accidentally. 20:00 I really cannot understand the need for "operator to intentionally slow down". The brake lights is to signal other people about the fact of slowing down not to advertise intentions.

@SirBlastalot Modern cars are supposed to flash the brake lights if heavy deceleration is applied. I think it would make sense to flash the lights according to ABS activation because that would clearly communicate how close to the maximal friction the vehicle in front of you is breaking.

@smilerjerg I drive manual, too, and I sometimes blink the brake lights manually even when the actual braking is engine braking only.

As a software developer with 20+ year experience, I can tell you that majority of the software developers will always implement the easiest solution that fulfills the requirements. There's no pride for your work for most developers I've met so there's no need to think how the brake lights should work. As the driver cannot see the brake lights, it's typically ignored except from the regulations. And when regulations have the word "MAY", that part will be left out from the requirements for the software.
