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.

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

[–] njordomir@lemmy.world 17 points 5 days ago

Can we do this in the same bill as the popup spikes that take out your tires if you stop across the crosswalk? The guided RPGs replacing red light cams can wait a little longer.

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

[–] Rexios@lemmy.zip 10 points 4 days ago (3 children)

Anyone complaining about lane keep not letting them change lanes or make turns is telling on themselves

[–] xthexder@l.sw0.com 6 points 4 days ago

There are a couple situations where it's annoying and I turn it off. My truck has the "steer back into lane" style assist, but it's tried to push me off the road before while I was towing a trailer on some narrow 1-lane roads. Some of the corners it's just not possible to get around without touching the center line.

The vast majority of the time it stays on though and is quite helpful.

Couldn't we just use the point system from 5th element? The car noticed you did something illegal and dedicated from your point pool.

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

[–] catloaf@lemm.ee 22 points 5 days ago

I mean when a car is coming at me from a cross street, I want to be able to tell if they're turning or just an asshole not using their signal. On some cars, the turn signal is mounted so far to the side that if they're approaching from my right and turning right onto the same street as me, I can't see that turn signal. Sometimes combined with the roundness of the nose exacerbating the problem.

[–] SaltSong@startrek.website 6 points 5 days ago (4 children)

I think what he wants is the front turn signal to wrap around the front, so I can see the left signal from the right quarter.

I'm not aware that this is not the case, but I don't know that I would have noticed if it was not.

[–] sugar_in_your_tea@sh.itjust.works 3 points 5 days ago (3 children)

Isn't that the case for pretty much everything? Newer cars alternate blinking their headlights and the signal indicator, and even cars w/ the turn signal on the side will have some light bleed through since it's all one assembly. In the majority of cars, I can see their turn signals when they're perpendicular to me. The larger issue is that most people in my area don't bother to use their signals in the first place.

i don't think that was ever required in the US. it is elsewhere though.

[–] SaltSong@startrek.website 5 points 5 days ago

Can't speak to "required." But I know it used to be done.

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.

[–] Gerblat@lemmy.world 44 points 5 days ago (1 children)

Heads up, it’s actually keyboard and chair, not keyboard and computer

[–] NocturnalMorning@lemmy.world 4 points 5 days ago

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

[–] drbluefall@toast.ooo 10 points 5 days ago (2 children)

I've always heard it as "PICNIC"

Problem In Chair, Not In Computer

And never forget about the I-D ten T error.

ID10T for those who didn't get it.

Layer 0 obfuscation error.

Oh, you think I need a new chair? Will the Internet come back then?

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

[–] acosmichippo@lemmy.world 4 points 5 days ago* (last edited 5 days ago) (1 children)

How would you do that so it isn’t ugly as hell

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).

[–] floo@retrolemmy.com 2 points 5 days ago (3 children)

This wouldn’t really be helpful to those who are colorblind.

[–] Trashboat@lemmy.blahaj.zone 5 points 5 days ago* (last edited 5 days ago) (2 children)

Somebody better tell traffic light designers

< and > for turns. X for brakes.

Honestly, we should focus on functionality rather than aesthetic.

[–] sour@feddit.org 1 points 4 days ago (1 children)

That doesn't answer the question. The question is how you would design it so you can look at the left side of a car, know that it's turning right and isn't prone to misunderstandings.

Up and down arrows? Up is away from you and down is towards you.

[–] sugar_in_your_tea@sh.itjust.works 2 points 5 days ago (5 children)

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.

Some of the new Kias have the rear indicators in the bumper. Why are they hiding them?

[–] catloaf@lemm.ee 3 points 4 days ago (1 children)

Because the designers and marketers were given priority over the safety engineers.

[–] Almacca@aussie.zone 1 points 4 days ago

And anyone that drives cars ever, apparently.

[–] moakley@lemmy.world 2 points 4 days ago

So it sounds like you're checking to see when the light turns off, to know that the car is going.

Sounds like what we actually need is a green accelerator light on the front of the car.
