Most of what is happening on that video appears to be a human controlling the vehicle, the overlay is just what the computer sees. In current public releases autopilot only warns you that it thinks you are going to run a red light / stop sign. And it is up for the human driver to actually stop. So, unless its on some beta release it was probably a human that rolled through it.

> warns you that it thinks you are going to run a red light / stop sign I need this feature, and I would prefer this to full autonomous driving. A computer that warns you when you're about to make a mistake is achievable today and will increase safety for everyone.

This. I expect this to be the near term outcome of a lot of autonomous driving projects, which is one of the reasons that despite my scepticism about the idea we're close to abandoning the steering wheel I still think the research itself is inherently worthwhile when conducted safely.

It still strikes me why so many people are still against a future with self driving cars. Sure, people throughout history are scared of change & new tech. But if you look at this video and compare the amount of stuff the camera catches AND processes, with the things you are seeing & processing, it's really hard for me to see me being better at it than a computer. The reality of driving (as a human) is that most of it…

There's no evidence that computers are any better at driving than humans, and there is no evidence that this generation of machine learning will be able to tackle this problem sufficiently. All signs point to driving requiring an understanding of what's going on around you, which this generation of ML does not provide. On the other hand, there is a lot of hype and promises being made without the results to back them…

Isn’t there already a mounting amount of statistics of accidents of self driving cars vs manual ones and the difference is night and day that the self driving ones are statistically safer?

Maybe this is ridiculous, but is it feasible that Tesla plans to use the SpaceX Starlink satellites to offload data for processing remotely?

Unlikely, too risky. Even the slightest glitch in the network could be disastrous. The car has to be at least smart enough to pull over and stop safely.

When talking about computation being a power drain, one could imagine a scenario where certain computations that can deal with the latency of starlink internet could be offloaded by default to the cloud. When a network failure is detected or results take too long to come in, the on-board computer could still take over the same computations, resulting in more power drain for a short moment.

This is a problem even in production autopilot in Teslas. When stopped at a stop light, you can see cars "dancing" and rotating randomly in a jittery fashion. Today during an auto lane change, the system blinked a truck from two lanes across in and out of my target lane, causing the car to cancel going into an empty lane after quarter ways entering it, twice.

The dancing cars were fixed several months ago in an update. The computer used to just recognize cars, and then align them according to the lanes it sees. At a stoplight it when it had trouble seeing the lanes clearly the cars would rapidly change orientation. Since they updated the neural net to also recognize the vehicle orientations the dancing has stopped. I have seen a lane change cancel recently, a couple weeks…

I'm pretty sure that they "fixed" the dancing cars problem by applying a low pass filter to the data before sending it to the visualization, just so people would stop complaining about it. I think there's still a lot of jitter in the underlying data.

Do you know if, when a vehicle disappears, the system assumes the vehicle continues moving as it was when last spotted?

The cameras are running at higher fps, but the processed outputs don't need to go that fast. At 65MPH, 18fps is one frame for every 5 feet of travel.

Not fast enough to react to someone swerving into your lane.

Cars don't tend to jump sideways all of a sudden (and if they do, then usually by outside force, which tends to be hard to avoid). There's plenty of frames to detect that (note that the view shown is not the only camera, otherwise making a turn safely would be fairly impossible).

That's a vacuous statement. Evidence would be a deployed self-driving fleet. At which point it would be mission accomplished and we wouldn't be discussing this.

Now if you want theoretical considerations instead of evidence, then consider the lower reaction times of machines.

When the alleged dangers are scary/obvious, and the benefits hard to comprehend, easy to oppose. I remember when credit cards, caller ID, online shopping, tax software, etc were all new. Each was loudly denounced as evil for various reasons; eventually the benefits became so obvious that we all now use those techs with little concern - even though many/most of the concerns were warranted. Just became too convenient t…

Most people have 0 experience with it, and 0 experiences seeing it (at least that they are aware of).

If you gave a random sample Tesla-level autopilot with their current car and walked them through how to use if, I'd guess that at least 75% would want to use it regularly.

Familiarity and basic understanding work wonders on shifting the human mind.

Dancing isn’t completely gone - especially with large trucks.
