Re: Camera vs. Lidar
#2But remember that accuracy of drawing bounding boxes around objects in still frames is only very slightly related to actual self-driving ability, even if intuition suggests otherwise.
This is basically just an ad for Scale and Scale's services, which include... drawing bounding boxes around objects in still frames.

#3This completely neglects the fact that humans can build near perfect 3D representations of the world with 2D images stitched together with the parallax neural nets in our brain. This blogpost briefly mentions it in one line as a throwaway and says you'd need extremely high resolution cameras?? Doesn't make sense at all. Two cameras of any resolution spaced a regular distance apart should be able to build a better parallax 3D model than any one camera alone.

I think most of our ability to judge relative distance is based on our brains judgement of lighting, texture, inference, and sound. While having two eyes helps a lot, you can still navigate a complex office environment with one eye closed. It just takes a bit more care.

There are also depth cues from https://en.wikipedia.org/wiki/Vergence#Convergence, right? As in focusing on the object itself?

> humans can build near perfect 3D representations of the world
The idea that the human brain has a "near perfect" 3D representation of one's surroundings seems inaccurate to me. There's a difference between near perfection and good enough that people don't often get hurt, when all of their surroundings are deliberately constructed to limit exposure to danger.

When I was younger I remember hearing about how we can do all these things because we have 2 eyes. And that depth perception is what gives us the ability to not walk into walls, and do other things including driving.
I have thought about this many times and often wondered why when closing one eye I am still able to function.
Sense then I have thought strongly that having depth perception is used for training some other part of our brain, and then only used to increase accuracy of our perception of reality.
Further proof of this is TV. Even on varying sized screens humans tend to do well figuring out the actual size of things displayed.

About 10 years ago I went to an eye doctor with a small object in my eye, and she had to cover it after removing the small object.
Driving back home with 1 eye was scary even though I was going much slower. It is possible to drive with 1 eye, but much much harder than with 2 eyes.

#10I suspect this is yet another story sponsored by the Tesla shorts. Just saw an excellent two hour interview by Lex Fridman of George Hotz and he goes into details why he thinks camera will win over lidar.
But he also admits that presently Google is ahead of everyone in the race for level 5, but raises the question of whether they can ever do it economically enough to make money on it?

Money quote is when Lex tells him, ""Some non-zero part of your brain has a madman in it"
I'd argue that is true of many of the greatest inventors of our time.
