Awesome! Now do it again and when it passes one set of parked cars on the side, have someone roll a soccer ball in front of the Tesla. Will the car assume a child will follow from in between the cars or not?

Say what you want, but you would never be able to avoid a crash like this: https://www.youtube.com/watch?v=oqHtavx-eec Or this https://www.youtube.com/watch?v=2uqA9bqICEk

I think the first might just look difficult to avoid because if the lack of peripheral view in the video- a driver would have seen the other car much earlier than the video suggests.

As for the second one, looks like the other car just passed in front of it.

> Source? If you simply refer to it being called "autopilot", cmon that's not too serious The Model 3 Builder literally says: "Full Self-Driving Capability".

Did you just read the one sentence and not any other text on that page?: "Coming later this year: Automatic driving on city streets.", Oh and how about "The currently enabled features require active driver supervision and do not make the vehicle autonomous. The activation and use of these features are dependent on achieving reliability far in excess of human drivers as demonstrated by billions of miles of experience,…

You mean the text in smaller face "disclaimer text" buried under the fold, well under the price and the "Prices are likely to increase in the future" ("BUY NOW!"), and below things like:

> Summon: your parked car will come find you anywhere in a parking lot. Really.

(It may plow into a street to do so, but hey. And you should really have "full attention" on the car. Unless you're reading our marketing copy which says to feel free to "attend to a fussy child")

and so on. Ninety per cent of the length of that page is selling promises that aren't there yet, and the fine print at the bottom is taking most of it away, for some indeterminate period of time.

Unless you're driving in a place known for courtesy like Canada or Hawaii ಠ_ಠ... People often stop late and won't move until you go first...

My father taught me this trick -- if you're going to arrive simultaneously, just make sure you stop clearly second (especially if the other car is on your right). I find it is usually pretty efficient and have yet to notice someone doing the same to me at the same time.

Hey I really like that! I often feel awkward at these where it is ambiguous who among 3 people actually stopped first. Not to mention people who roll right through without stopping (when other cars are present.)

I’m kind of impressed by how smooth it is, actually. If you watch videos of state-of-the-art object localization NNs, they tend to be EXTREMELY jumpy. These neural nets usually operate on only a single frame at a time, at least in the lower layers, so their predictions tend to jump around a lot from frame to frame (especially when the camera is moving!)

It worries me in general though, and I think that a higher level of consistently in the results of the parts of the image that don't significantly change between frames seems like a goal worth pursuing. I also think that a deeper understanding of the mechanisms and techniques required to reduce jitter might offer some insights into ways of handling adversarial images.

And I do mean insights and not a potential solution. I think it's an issue related to the handling of the spatial discontinuities introduced by the conversion of an effectively continuous reality into a representation consisting of a large number of discrete elements.

I think a more in depth understanding of how to navigate organically introduced discontinuities could provide a baseline against which we can look to combat the maliciously introduced ones.

It most likely won't be enough - since the problem source is an adaptive and intelligent adversary.

I wonder why they would let the public see this. To the critical eye it looks like it barely works. It loses its mind right at the beginning, around 0:06-0:07, veers to the right for no reason and then rolls through a stop sign without stopping. It spends the rest of the video hunting left and right like a drunk.

> It loses its mind right at the beginning, around 0:06-0:07, veers to the right for no reason I'm speculating but I think the reasons it veers to the right are some combination of the following: 1) There is water on the left hand side of the lane. I was going back and forth on the video and you can see "Raining" along the left edge turn green. So, it has detected the water and is avoiding it? At the same time it has…

At the same time it has turned green "Wet road". 2) There is a vehicle on the right side of the lane - it has been identified with an upside down green triangle / crosshairs and a square (is that block the license plate?) and the Tesla is "following" it.

"May potentially swerve into other lanes to avoid puddle"?

And yeah, it literally runs a stop sign. In their own marketing video.

Some have speculated that it's a human driving and not autopilot (plus autopilot still has a warning that it's only meant for highways).

> plus autopilot still has a warning that it's only meant for highways

And Summon has a warning that you need to "pay full attention to the vehicle".

Unless you look at their marketing, in which case it also tells you that you car will come "as you are being distracted by a fussy child".

I believe this was released as part of Tesla's Autopilot hiring announcement. More details here: https://www.tesla.com/autopilotAI Definitely someone's dream job ;) I particularly like the applicant query: "Tell us, what extraordinary work you have done?"

Two issues, first: I thought fully autonomous driving was meant to be done by now? Second, don't Tesla & SpaceX have a reputation for being a terrible place to work, with Musk expecting everyone to be working as hard (or harder) than him, and firing people in weird and capricious ways.

>I thought fully autonomous driving was meant to be done by now?

Musk was bullshitting when he made that prediction. Maybe he did it because he had bought his own bullshit. Personally I think what's more likely is that he was cynically conning people.

In reality, I think no-one is anywhere close to fully self driving cars. I would be surprised if we saw fully self driving cars any time in the next 50 years.

The whole field of fully self driving cars has been astonishingly full of empty hype, for some reason often believed by otherwise quite smart people.

Tesla and SpaceX, specially SpaceX has been rated very highly in some rating I have seen. But there is a reputation that it is a lot of work specially in crunch time.
