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

It's doesn't matter, since the absence or presence of light would still be perceived by colour blind people. It doesn't change how they would drive, as they are already driving with the knowledge of colour blindness in mind when looking at tail lights.

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.

I still think rear signaling could be improved dramatically by using a wide third-brake light to show the intensity of braking.

For example -- I have seen some aftermarket turn signals which are bars the width of the vehicle, and show a "moving" signal starting in the center and then progressing towards the outer edge of the vehicle.

So now take that idea for brake. When you barely have your foot on the brake pedal, it would light a couple lights in the center of your brake signal. Press a little harder and now it's lighting up 1/4 of the lights from the center towards the outside edge of the vehicle. And when you're pressing the brake pedal to the floor, all of the lights are lit up from the center to the outside edges of the vehicle. The harder you press on the pedal, the more lights are illuminated.

Now you have an immediate indication of just how hard the person in front of you is braking. With the normal on/off brake signals, you don't know what's happening until moments later as you determine how fast you are approaching that car. They could be casually slowing, or they could be locking up their wheels for an accident in front of them.

Japan introduced brake lights that increase intensity based on how hard the driver was braking. 20+ years ago. They tested it in the US and drivers found it to be “confusing.”

Tail lights being red is fine if you live with the most common forms of colorblindness which fall into what we call “red-green colorblind.” It is still a different color than headlights.

Now put those same red-green lights on the front, and we have a problem.

Here's an idea. How about we zap the drivers after they make a turn if they didn't use a turn signal beforehand?

The key detail is that, like with rear brake lights, they extinguish when the foot is removed from the brake pedal. So it's not so much the presence of the brake light, but the presence of an inactive brake light that would, serve as a warning that a car is about to start moving. This would be very helpful to drivers on a road when other drivers are pulling out too early from a side road or driveway. That little bit of extra warning is, in many situations, enough for you to pump the brakes, hit the horn, or both.

Cars with lane-keep assist with vibrate the steering wheel and beep at you. It's at least something but I think most people turn it off if it gets annoying

I don't think they illuminate the brake lights, hence my comment. Technology connections has talked about this, although IDK which video it was.

This is actually insane. Their brakes must wear out so fast.

They tested using a green light for the front brake light, not a red one

Again, if you're too stupid to make sure the multiton hunk of metal is coming to a stop by all the other obvious visual markers, including watching it's speed compared to stationary objects like signs and lamp posts, then this won't do shit. People need more aweness of their surroundings, not a bunch of lights and horns because people won't pay attention.

You enter the road when it's safe, not jump in and play frogger with lights hoping to get across.

It used to be mandatory with always on rear lights in Sweden (you couldn't even turn them off). But an adaptation to EU rules removed that requirement.
