Which are a tiny minority. The largest causes of crashes in the US are attention/cognition problems, not vision problems. Most traffic systems in western countries (probably in others, too, but I don't have personal experience), and in particular the US, are designed to limit visibility problems and do so very effectively.
Regardless it is irrelevant to the point. Whatever the number may be, lapses in human visual perception are responsible for some crashes
That sounds like a personal opinion?
Maybe do the bare minimum of research before spouting yours.
DOT says that only 5% of crashes are caused by low visibility during weather events.[1]
In 2023, the combined causes of alcohol, speeding, and distracted driving (all cognitive/attention issues) caused 67% of highway deaths. [2]
I was able to find these in 30 seconds. You did zero research to confirm whether your belief was correct before asserting that my claim was opinion. That's pathetic.
> Regardless it is irrelevant to the point.
And your point is therefore irrelevant to the discussion at hand, because the person you were replying to did not claim that vision had no safety impact, but that it had little safety impact:
> the issue is clearly attention not vision when it comes to humans. if we could actually process 100% of the visual information in our field of view, then accidents would probably go down a shit load.
...and, as we can clearly see, the issue is attention (and some bad decision making), not vision.

“Low visibility during weather events” is a small subset of this.
A ridiculously common example of the limitations of human vision is when people hit curbs parallel parking because of the inherent limitations of relying on depth perception to estimate the exact location of the vehicle when it cannot otherwise be directly seen. Go look in a parking lot and see how common curbed wheels are.
Also, NHTSA estimates that they don’t have any information for 60% of incidents, because they go unreported.
> “Low visibility during weather events” is a small subset of this.
You're still refusing to do the most basic research or even read my comment:
> In 2023, the combined causes of alcohol, speeding, and distracted driving (all cognitive/attention issues) caused 67% of highway deaths.
Do the math. 100% - 67% is 33%. Even literally not opening Google, you can already deduce that the maximum fraction of fatalities caused by vision is 33%.
Given that you aren't interested in reading or researching and instead just want to push your opinion as fact, I think your claims can be safely discarded.
Edit: Because you're editing your comment because you realize that you're making an absolute fool of yourself:
> A ridiculously common example of the limitations of human vision is when people hit curbs parallel parking
A completely irrelevant distraction - this causes virtually zero accidents and even fewer fatalities, and you know it.
> Also, NHTSA estimates that they don’t have any information for 60% of incidents, because they go unreported.
Aha, so now you actually did research, and found that all of the available data supports my claims, so you're attempting to undermine it. Nice try. "Estimates" vs. actual numbers isn't really a contest.
Come back when you have actual data - until then, you're just continuing to undermine your own point with your ridiculous fallacies and misdirections - because if you actually had a defensible claim, you'd be able to instantly pull out supporting evidence.
I'm not arguing about fatalities or relative percentages of contributing factors, nor am I arguing that alcohol/speeding/attention are not all also issues. They are, you're right.
The only thing I argued is that "lapses in human visual perception are responsible for some crashes", which is a fact.
* someone parking carefully, misjudges depth perception, bumps an object
* person driving at night, their eyes failed to perceive a poorly lit feature of the road/markings/obstacles
* person driving and suddenly blinded by bright object (the sun, bright lights at night)
* person pulling out in traffic who misinterprets their depth perception and therefore misjudges the speed of approaching traffic
* people can only focus their eyes at one distance at a time, and it takes time to focus at a different distance. It is neither unsafe nor unexpected for humans to check their instruments while driving -- but it can take the human eye hundreds of milliseconds to focus under normal circumstances -- If you look down, focus, look back up, and focus, as quick as you can at highway speeds, you will have travelled quite a long distance.
These type of failures can happen not as a result of poor decision making, but of poor perception.
Most of them.
We can lump together "inattention" and "idiocy" for the purposes of this conversation, because both could be massively alleviated by a good self-driving car without lidar.
If you look at the parallel comments, you'll see that the majority of accidents and fatalities indeed come from these two factors combined (two-thirds coming from distraction, speeding, and impaired driving), and that kube-system is having to resort to ridiculous fallacies to try to dispute the empirical data that is available.
However, there is also a lot of interaction between our perceptual system and cognition. Just for depth perception, we're doing a lot of temporal analysis. We track moving objects and infer distance from assumptions about scale and object permanence. We don't just repeatedly make depth maps from 2D imagery.
The brute-force approach is something like training visual language models (VLMs). E.g. you could train on lots of movies and be able to predict "what happens next" in the imaging world.
But, compared to LLMs, there is a bigger gap between the model and the application domain with VLMs. It may seem like LLMs are being applied to lots of domains, but most are just tiny variations on the same task of "writing what comes next", which is exactly what they were trained on. Unfortunately, driving is not "painting what comes next" in the same way as all these LLM writing hacks. There is still a big gap between that predictive layer, planning, and executing. Our giant corpus of movies does not really provide the ready-made training data to go after those bigger problems.

This company claims their LIDAR works conservatively at 250m, and up to 750m depending on reflectivity

We often greatly underestimate / undervalue the role of our ears relative to vision. As my film director friend says, 80% of the impact in a movie is in the sound
You're listening to the road and car sounds around you. You're feeling vibration on the road. You're feeling feedback on the steering wheel. You're using a combination of monocular and binocular depth perception - plus, your eyes are not a fixed focal length "cameras". You're moving your head to change the perspective you see the road at. Your inner ear is telling you about your acceleration and orientation.
