I wonder, do they upload all the camera videos taken during driving in grayscale low-res video through 4G to be computed though their neural net at Tesla ?
What hardware do they have in the car to process the video, the Jetson TX1 can use up to 6 cameras or 1400 Mpix/s, but they probably use low-res output for neural net usage.
I wonder what drivers think of their privacy.

Re: All Tesla Cars Being Produced Now Have Full Self-Driving Hardware
#282Will this new neural net and hardware be capable of advanced object detection? For instance if a plastic bag or piece of cardboard rolls across the highway a human driver knows it's safe to run over without stopping. Would a system like this just see an obstacle via radar and emergency brake? Google has been working on this problem for longer and they have access to the largest image/video datasets in the world to tr…
What I would find more interesting is if neural nets are even a valid way to built automotive components for self driving cars.
Safety critical components in most of the industries are currently very heavily built around the idea of being deterministic, so that you exactly know what will happen for a specific input and when it will happen. And of course also where the behavior from requirements can be found in code and all this process stuff. Neural networks from my point of view (only university knowledge) seem however more like blackboxes, where you don't exactly know how they will behave in the end.

I'm not sure I entirely agree with that. Cars are already extremely risky to modify, but it is still possible (and it's even a protected consumer right). I can go out and accidentally cut the breaks on my own car while changing the tire, if it causes harm, we already have a system in place to deal with it. Why should software be any different?
I would argue that cars are not extremely risky to modify mechanically - the parts are usually large, almost everything you'd want to do on your car has youtube videos and forum threads with people doing the exact same procedure, and you have pretty immediate feedback if you really messed anything up/the car is inoperable. I don't think that is the same for self-driving software if you were allowed to hack it. It is…
It's not a your business unless you will be hit by such car.

>In terms of safety, people will still lose their lives, they will just die from different kinds of car accidents than the kinds we have now If self driving cars kill 20 thousand people a year, it would still be a major improvement. 30 thousand people die every year from human drivers.
Nah because the human stat is for the average human. Being above average means I'd rather have control.
Studies have shown[1] that most people think they're an above-average driver, so your statement isn't very convincing. This cognitive bias is called Illusory superiority (https://en.wikipedia.org/wiki/Illusory_superiority).
[1] Here's one that says 80% of people rated themselves above-average on a number of important driving characteristics - http://www.sciencedirect.com/science/article/pii/00014575869.... And it's easy to find many sources saying that this conclusion has been reproduced time and time again.

Computers don't have fatigue. Ever driven for 12 hours? I have. I was so exhausted, I couldn't tell how much of safety hazard I was to everyone else. Humans fuck up like that. Even if computers can only match humans at skill level, they will be at the skill level 100% of the time, no directions. (And they will probably exceed us in skill anyways) Car accidents don't happen because people lack skill nearly as often as…
I've driven 12 hours a day for 5 days straight (going 3000 miles cross country). Didn't have an issue.
Just because you didn't have an accident doesn't mean your risk of having one wasn't significantly higher (it almost certainly was).

#286I think what people are missing here is an understanding of how these systems are tested and deployed at scale. While I have no involvement with Tesla I do have first-hand knowledge of similar programs at tier 1 automotive suppliers. The suppliers provide (or are looking to provide) an electronics suite to car manufacturers. The car manufacturers want the system to be safe lest they be sued out of existence. One part…
Question: Does the fact that the collection of the required volume of kms driven is performed over a shorter period of time based on a higher number of test subjects collecting the data impact the diversity and quality of the data negatively? Said another way: Is there a downside to parallelizing the collection process across a broader horizontal population of collection vehicles over a shorter period versus the trad…
The question whether a time average over a long period of a random quantity in one system and an average over multiple systems over a short period are the same is the question for ergodicity [1]. If both are the same, the random process or system is called ergodic.
The answer is: If the measurement period for the average over multiple systems is long enough that each random variable has visited a representative sample of states which make up the majority of contributions to the mean value, then the system is ergodic.

Your average car driver gets a few weeks of training at age 15 or 16 and a cursory written test. What does a pilot get?
Wow what country are you in where you only get a few weeks of training? It's a year+ in Australia.
Same in the UK. There's no mandatory number of hours lessons you need to accumulate before taking your test; if you (somehow) pass having had no lessons at all you're good to go.

I am going play devil's advocate here.
In the future, would Telsa use these data for other purposes? ie after analysing the data, it finds that my driving behaviour risk and has a higher chance of accident. It could trigger high insurance premiums or restriction on which car I can purchase etc.

Yes, it will be processed live in the car. From the article:
> To make sense of all of this data, a new onboard computer with more than 40 times the computing power of the previous generation runs the new Tesla-developed neural net for vision, sonar and radar processing software.
In the beginning, it's very likely some data will be uploaded in bulk, for Tesla to analyze, particularly while they are running the passive tests to correct their models.
