Not to mention that when you can't see, you slow down? Does the self-driving system do that sufficiently in low visibility? Clearly not if it hit a pedestrian with enough force to kill them.

The article mentions that Tesla's only use cameras in their system and Musk believes they are enough, because humans only use their eyes. Well firstly, don't you want self-driving systems to be better than humans? Secondly, humans don't just respond to visual cues as a computer would. We also hear and respond to feelings, like the sudden surge of anxiety or fear as our visibility is suddenly reduced at high speed.

Unfortunately there is also an AI training problem embedded in this. As Mobileye says, there are a lot of driver decisions that are common, but wrong. The famous example is rolling stops, but also failing to slow down for conditions is really common.

It wouldn't shock me if they don't have nearly enough training samples of people slowing appropriately for visibility with eyes, much less slowing for the somewhat different limitations of cameras.

I think one of the reasons they focus only on vision is basically the entire transportation infra is designed using human eyes a primary way to channel information.

Useful information for driving are communicated through images in form of road signs, traffic signals etc.

I dunno, knowing the exact relative velocity of the car in front of you seems like it could be useful and is something humans can’t do very well.

I’ve always wanted a car that shows my speed and the relative speed (+/-) of the car in front of me. My car’s cruise control can maintain a set distance so obviously it’s capable of it but it doesn’t show it.

[dham]

If your car is maintaining speed of the car in front then the car in front is going speed that is showing on your speedometer.

[nkrisc]

Yes, that’s true, but I don’t see how that relates to my comment at all.

I said the relative speed. If the car is going the same speed as me then the relative speed is 0mph. I want to see that when I’m not using cruise control.

We are "designed" (via evolution) to perceive and understand the environment around us. The signage is designed to be easily readable for us.

The models that drive these cars clearly either have some more evolution to do or for us to design the world more to their liking.

[hshshshshsh]

Yes. I was talking why Tesla choose to use vision. Since they can't control designing the transport infra to their liking at least for now.

[freejazz]

That's not a reason to only use vision.

[hshshshshsh]

I said one of the reasons. They probably did some cost analysis and realised it's not worth spending engineering effort on other modes when human drivers are able to drive around pretty much using only vision.

[freejazz]

I didn't say it was the only reason. Re-read my comment.

> They probably did some cost analysis and realised it's not worth spending engineering effort on other modes when human drivers are able to drive around pretty much using only vision.

Humans and cars aren't equal so this is just incredibly misguided as a principle.

[plorg]

I would think one relevant factor is that human vision is different than and in some ways significantly better than cameras.

[pmorici]

The Tesla knows when it's cameras and blinded by sun and act accordingly or tells the human to take over.

[kelnos]

Expect when it doesn't actually do that, I guess? Like when this pedestrian was killed?

[eptcyka]

If we were able to know when a neural net is failing to categorize something, wouldn’t we get AGI for free?
