Elon may have been technically correct about 'if humans can do it with vision only then theres no reason why vision-only cannot work' but turned out to be the wrong strategy for learning how to get there. lidar gives you a constant stream of data to check your vision yourself against and interatively learn. Once trained you turn it off. whereas teslas strategy ended up having to rely on human drivers for error feedback which made the learning loop way longer.

I don't think you can just look at the statistics though. What I mean is that, the main issue is that the category of mistakes they make are going to be inherently different from the category of mistakes that humans make. IE, humans are more likely to make emotional mistakes, but self driving is probably more likely to make perceptual mistakes or fail to respond to novel situations. I think the "fail to respond to no…

Or a 0.5X% chance of a loved one dying from a ML-category mistake? I would take the latter in a heartbeat. Why…
While I agree with you, not everyone does.
You and I are thinking with a purely logical thought process, but most people don’t reason that way.
A lot of people want to be able to hold someone accountable, and that is more important than the pure probabilities.
They want to be able to blame a person for making a mistake.

It's very interesting, because on one side we have clear data showing that autonomous cars at the Waymo level are safer than humans. On the other hand we don't give technology the same pass we give to humans, meaning that we don't tolerate machine incidents the same way we tolerate human ones. Which means that self-driving cars need to be a magnitude of order safer than humans. And even though a self-driving car will…
When a human driver messes up, there's a person to hold responsible. When a robot car messes up, who is held responsible? If the human messes up to the point they are no longer allowed to drive, that person is no longer on the streets to cause more mistakes. When a robot car messes up, are all of the other cars pulled off the streets as well until the glitch is fixed? Every robot car is essentially the same driver.
Mistakes aren’t glitches when the environment is so dynamic. I imagine they are making errors constantly, and constantly learning from them.
When a robot car makes a mistake, all robot cars learn from the experience. When a human messes up, only that human learns from it.

#145Why are the cars so big? Wouldn't it make sense to have a bunch of much smaller, single person vehicles?
Tesla Cybercab has about three or four times the efficiency and like a fifth of the price by having smaller, two person vehicles. Indeed, the vast majority of trips are taken by single people and it's ridiculous to have a giant machine for them. It would also be okay to have a handful of larger, Model Y-sized vehicles for the multi-person trips. To actually answer your question: Part of the reason why the Waymo cars…

I read this as Tesla Cybertruck and was mightily confused for a minute.
Looking it up in Wikipedia I see it has no driver support (steering, pedals, etc). Is that even road-legal?

While we hold humans financially responsible for all accidents, we don’t hold them personally responsible in every case. Most accidents end with no arrests or even tickets. If your hand slips on the steering wheel, you don’t go to jail.
Robot cars would be the same. Insurance is financially responsible, and if the accident is deemed caused by a flaw, it would be the company that made them that is held responsible for fixing it.

#147Here in Austin, I'm stuck calling an uber and hoping I get a Waymo. When does that deal expire?
It is so so so so so so bad to have to risk an uber every time I want to hire a Waymo.
I have still not gotten a Waymo even once. I am in the service area. I don't use the service frequently, just enough to be disappointed.

#148Re: Waymo in Dallas
#149I live very close to LAX, and we have hundreds of Waymos in our area. At first i was a little weary, and kinda weirded out by all of them. They have become completely normal, and cause WAY fewer traffic incidents than human drivers. They are very predictable, and will always let you pull in front of them when changing lanes (unlike a lot of other LA drivers). I have seen a few incidents where they seem 'stuck', and i…

> a magnitude of order
unless I'm missing something, you meant "order of magnitude"
