Eyes can’t see in low visibility.
musk “we drive with our eyes, cameras are eyes. we dont need LiDAR”
FSD kills someone because of low visibility just like with eyes
musk reaction -
It's worse than that, though. Our eyes are significantly better than cameras (with some exceptions at the high end) at adapting to varied lighting conditions than cameras are. Especially rapid changes.
Hard to credit without a source, modern cameras have way more dynamic range than the human eye.
Not in one exposure. Human eyes are much better with dealing with extremely high contrasts.
Cameras can be much more sensitive, but at the cost of overexposing brighter regions in an image.
They're also pretty noisy in low light and generally take long exposures (a problem with a camera at high speeds) to get sufficient input to see anything in the dark. Especially if you aren't spending thousands of dollars with massive sensors per camera.
I dunno what cameras you are using but a standard full frame sensor and an F/4 lens sees way better in low light than the human eye. If I take a raw image off my camera, there is so much more dynamic range than I can see or a monitor can even represent, you can double the brightness at least four times (ie 16x brighter) and parts of the image that looked pure black to the eye become perfectly usable images. There is so so so much more dynamic range than the human eye.
Do you know what the depth of field at f/4 looks like? It's not anywhere in the neighborhood of suitable for a car, and it still takes a meaningful exposure length in low light conditions to get a picture at all, which is not suitable for driving at 30mph, let alone actually driving fast.
That full frame sensor is also on a camera that's several thousand dollars.
Not only that, when we have trouble seeing things, we can adjust our speed to compensate (though tbf, not all human drivers do, but I don't think FSD should be modelled after the worst of human drivers). Does Tesla's FSD go into a "drive slower" mode when it gets less certain about what it sees? Or does its algorithms always treat its best guess with high confidence?
if he was truthful: "the cost of adding lidar cuts in my profits"
Correction - Older Teslas had lidar, Musk demanded they be removed because they cut into his profits. Not a huge difference but it does show how much of a shitbag he is.
He really is a fucking idiot. But so few people can actually call him out... So he just never gets put in his place.
Imagine your life with unlimited redos. That's how he lives.
You'd think "we drive with our eyes, cameras are eyes." is an argument against only using cameras but that do I know.
How Can Cameras Be Real If Our Eyes Aren't Real?
What pisses me off about this is that, in conditions of low visibility, the pedestrian can't even hear the damned thing coming.
I hear electric cars all the time, they are not much quieter than an ice car. We don’t need to strap lawn mowers to our cars in the name of safety.
You can hear them, but manufacturers had to add external speakers to electric cars to make them louder.

The cars used to have RADAR. But they got rid of that and even disabled it on older models when updating because they “only need cameras.”
Cameras and RADAR would have been good enough for most all conditions…
