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.

And also like, used at all.

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 1 week 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.

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

[–] catloaf@lemm.ee 22 points 1 week 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.

Not selling tanks as cars could also help. Especially with fatality rates

I'd rather see mandatory rear running lights. The amount of people who can't be arsed to turn on their lights in bad visibility conditions is too damn high.

and on the opposite side don’t turn on your emergency lights while driving in bad weather. you’re only causing confusion by making it seem like you have turn signals on if i can’t see both blinkers.

The hazards also override your turn signals so I now have no idea when you are going to attempt lane change.

[–] prettybunnys@sh.itjust.works 16 points 1 week ago* (last edited 1 week ago) (4 children)

The hazards are to indicate you are stopped and now a hazard.

Only when you are stopped and now a hazard. Your car becomes a blinking light. We have road rules for blinking lights, so it SHOULD be saying one specific thing.

Thank you for coming to this road safety talk.

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.”

probably because thats a terrible way to do it. It would be noticeable if a car started braking and then started braking much harder, but if they slam on the brakes you don't see anything change, just a normal brake light.

First of all, this would be illegal in many countries.

Second of all: we can differentiate cars by: has red lights, back.

If we lose this option we can no longer differentiate easily if there is a car coming towards us or driving away from us.

[–] CosmicGiraffe@lemmy.world 29 points 1 week ago (2 children)

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

It is to colorblind people. You could use something else of course, just saying...

I don't understand this at all. Why do I, as a person in front of a vehicle, care whether or not it's braking?
