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.

How would you do that so it isn't ugly as hell and isn't prone to misunderstanding?

I've seen newer cars turn the headlight off while the turn indicator is on, so you get a sort of double-blink effect.

I don't see any reason why we can't just have the whole headlight blink yellow as well with the turn indicator. LEDs are everywhere and can handle changing colors really easily, so it's not hard to require that for all new cars.

Absolutely, but that doesn't solve the problem that's talked about here (seeing the turn signal from the other side of the vehicle). It might be clearer what the turn signal is, but if you look at the right side of a vehicle, you won't be able to see the left headlight, even when it's massive.

When am I ever looking at the side and needing to see the other side's turn signal? The best I can think of is (using right side driving) a car turning right into my lane of travel as I'm going straight, but I'll be a bit offset to the left and should be able to see the right headlight. If I can't, that means the car is angled to the right, making it obvious that they're turning.

Because this is what the discussion is about?

Personally I just want front turn signals to be visible from the opposite side again.

And I'm saying I can see them most of the time, and when I can't, I don't need to because their intention is obvious.
