I read the article and the next one comes up: "Mouse Sperm Structure Unveils Asthenozoospermia Mechanisms" and my co-worker was like wtf are you reading.

I think they should have it so there's a type of "slow down" light that supplements the brake light for when your deceleration is from taking your foot off the gas.
Perhaps a short paragraph of text elaborating on the driver's intentions

Please allow me this opportunity to jump in and complain about the minority, but not insignificant number, of people that don't seem to be aware that that is even an option (just taking your foot off of the gas/accelerator to slowly decelerate).
Every couple weeks or so I seem to find myself behind someone that's always either accelerating, or braking, with the brake lights repeatedly flashing on momentarily for no apparent reason. It's like they realize that they're going just a little faster than they want, and definitely don't want to accelerate any more, so the only thing they know to do is hit the brake, instead of just taking their foot off of the accelerator. So they've hit the brake and now they're going too slow, so foot moves off the brake and back to the accelerator. Rinse, lather, repeat.
End rant. Thank you for this opportunity to vent.
These people might be two-footed drivers. My mother used to do this and you'd see the brakes flash on and off while following behind her because she'd be hovering her foot on the brake pedal while also hitting the accelerator.

Brake light activates before the brakes engages, so they could just be resting their foot on the brake while coasting. Pretty normal defensive driving technique. People tend to do it in heavier traffic or when people are tailgating them. Gives a way faster brake response.

In many EVs and Hybrids the "letting off the accelerator" engages the regeneration drag which slows the car. A number of vehicle makers with particularly aggressive drag (which gets higher regen rates) automatically illuminate the brake lights. So if you're behind one of these it will look like they are braking when they may have no foot on any pedal (brake or accelerator).

Like someone said in the hnews comments, this might work for auto transmission but with manual gearing you've got people using engine braking on hills.
Also like stated in the article the colouring is going to be an issue and trying to see some green lights whilst the headlights are on (full beam fog lights perhaps too?) doesn't seem practicable to me.
with computers these days an acceleration based system should be achievable for all types of cars. hybrid/electric cars already do it with regen braking.
-
How would you do that so it isn't ugly as hell and isn't prone to misunderstanding?
sliding light or arrows

Those are definitely not people that ever learned to drive a manual transmission.

Theres a saying in computer stuff that applies nicely here. PEBKAC, problem exists between keyboard and computer...turn signals have to be turned on, no amount of engineering can fix bad driving.
Heads up, it’s actually keyboard and chair, not keyboard and computer

Possibly, and I'd be interested in some sort of 360° LED on top of a vehicle to indicate to pedestrians and other drivers alike of its (de)acceleration.
But jamming some non standard colours in what is a long term understanding on the front of a vehicle I can't really get with and would like to see the impact to people with partial / colour blindness with using such a system.
Like, does the average pedestrian know what the green and red lights mean on an aircraft? I bet not.

Rear fog lights on all vehicles (some vehicles have them now).
it's forbidden to use rear fog lights under rain (it's more confusing than helpful)
if you live somewhere dry, that's not a concern. But here it rains 1 day in 3

By signaling to oncoming traffic and vehicles approaching from the side, a front brake light provides an essential visual cue that a car is slowing down or preparing to stop. When the light is extinguished, it indicates that a stationary vehicle might initiate movement. According to Tomasch, this visual feedback can significantly truncate the reaction time for other road users, leading to shorter stopping distances and consequently diminishing the likelihood of accidents.
Sounds reasonable. Personally I just want front turn signals to be visible from the opposite side again.

Not sure if I read that correctly, but I don't think this has ever been the case?

same way we do with lights now, design them attractively. It is not always successful and that's on the manufacturers.
and isn’t prone to misunderstanding?
what about it is confusing? green = not coming at you so it's okay to turn left (or whatever).

Dang it, sometimes I just type stuff and dont think about what I typed (the irony of what I was writing out)

I just got a Chevy Volt and when I let up off the accelerator it will start the regen and significantly decrease my speed. I assume that my brake lights are coming on because so far no one has rear-ended me or yelled at me for not having brake lights. I wish there was a good way to tell for sure though. I think it's Hyundai that does not engage the brake lights for situations like this, as I've about hit one before.

Last I heard something like 98% of new cars/trucks sold in America have automatic.

I feel your pain -

Automatics also allow for engine braking. From a quick search, it sounds like a toss-up as to whether that triggers brake lights. Regardless, the article mentions the benefit is not only from cars slowing down, but also from indicating that a car is preparing to stop or "that a stationary vehicle might initiate movement". Neither of those can be done by an engine brake, so front brake lights would still have a benefit even with a driver that likes engine braking.

fair point about color blindness, but surely there is some 4th color that would work well with red/amber/white.

It would also help to know whether or not I'm going to get smushed.
