How do you think the propriety systems work?
Well, they're often (always? can't say that as I haven't gone all the way into all of them, I suppose) built using actual real-time systems with latency guarantees rather than Python running on off-the-shelf Linux, to start...

Re: Openpilot – open-source self-driving agent
#32I work as a lead autonomous vehicle engineer. Here's a few thoughts: * This isn't really open-source. The most important part, the neural network perception pipeline, is closed sourced. Without the training data and the network architectures, the supporting code is not that useful. * This system is non-deterministic, which is a no-no in critical systems like autonomous vehicle. There's no guarantee that vehicle detec…
What do you mean it's non deterministic? Because it is using floating point operations?
Can you elaborate?

#33One side of me thinks this is really, really cool. The other side is running away as fast as possible. If anything shouldn't be developed by committee, it's something that controls a few thousand pounds hurtling down the highway at 70MPH with at best an observant human watching over it. Here's my reasoning: Mistakes in Django? Bad things happen. Mistakes in the Linux kernel? Potentially really bad things happen. Mist…
Some might argue the transparency and eyeballs are even more crucial in such a situation.

Not a real-time OS?

Maybe they are talking about the numerical stability of the algorithms?

I'm not OP, but I think he means that the final decisions acted upon are not deterministic. So given an input, it won't necessarily produce the same decision every time.
For instance, if the model predicts with a 95% certainty to accelerate, then 5% of the time it'll do some action other than accelerating.

As long as it's statistically better than a human driver, it's all good. Human drivers fail all the time, resulting in mass casualties in every single country.

Yep, it seems built to run on NEOS, which is an Android distribution: https://github.com/commaai/neo

#39For those who haven't seen Openpilot before, or recently: * George Hotz (not "Hortz") is working on other stuff now [0], and is no longer CEO. * While "I'm running open-source self-driving software from GitHub" sounds terrifying, the software is very good at what it does, which is very limited (LKAS / ACC / driver monitoring).

Damn, I was actually planning on applying to Comma for an internship because George Hotz was there, just to see if I could learn anything from him.

No Tesla programmers have been arrested for Autopilot-related crashes.
Tesla makes it extremely clear to its users what the shared responsibility model is for Autopilot features (through warning messages at each Autopilot engagement and in the user's manual for all Tesla vehicles), and has general counsel on staff to reinforce this through legal actions indemnifying their staff. Openpilot is a drastically different model. It is a software breadboard for your own vehicle. For example, th…
Well, what you mention Tesla does is the disclaimer part, but what Elon boasts about is the headline/first paragraph part...
