The concept of a front brake light has been floating around the automotive industry for some time now. However, no vehicle manufacturer has yet embraced the idea and turned it into a reality on the
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.
I think that's a neat idea, but we could instead, collectively, just do better at following other cars at a safe distance. I know it's impractical to expect all drivers on the road everywhere to change their behavior, but it's also persistently frustrating as someone who has for years frequently been stuck in traffic to see 95% of drivers insist on following less than a car-length behind. Following too closely to enable decision-making or accommodate other drivers is the cause of like 98% of both traffic accidents and congestion, according to my completely anecdotal and made up research.
I suspect a lot of that has to do with the entitled way people are driving these days. If you leave a car length gap, some kid will wrecklessly attempt to cram their way in because your lane momentarily moved slightly faster.
There's this idea I've been considering for a long time.
Imagine putting a remote controlled firework smoke bomb under the tailpipe, hidden from sight. At best a really stinky one that smells like burned rubber or something.
When someone follows to closely, just fake an engine issue or something by activating the smoke bomb and fill their AC air intake with the smell of burned rubber for weeks. Just to teach them to not follow too closely again.
I think a secondary light that blinks quickly would be a good signal of emergency braking. Like some aftermarket motorcycle taillights that start with a blinking pattern before they stay on, but reverse the order.
So, standard brake light comes on at the standard time, at the first touch of the brake. For stronger braking, the second light comes on. For emergency braking, the standard brake light stays lit while the second light begins blinking frantically.
The EU has approved G-triggered brake lights that do just that, flash rapidly on hard braking. I’ve only seen it on higher end cars so far, but they absolutely exist. Unfortunately in the US people stick brake flashers that blink in patterns every time they touch the brake. Mostly useless as they’re installed to be “look at me, aren’t I cool with my blinky brake lights?” rather than any additional safety.
Seems much more complicated than having the brake lights rapidly flash during hard braking. But of course we couldn't do that in the US because our turn signals/hazard lights are red
