I think this topic deserves a thread of its own.

In September 2017, Mike and @Caleb Elston at the Tesla Show did an excellent podcast on Autopilot simulation (highly recommended listening).

I was struck by the huge potential this simulation stuff seems to have.

Please note that there's currently four job listings at Tesla.com that has to do with Autopilot simulation:
I'll mash up some quotes in case the links die:
Role:
Contributing to the development of Autopilot simulation through managing engineers, artists and subcontractors engaged in the creation of photo realistic 3D scenes that can accurately model the driving experience in a wide range of locales and conditions. Working directly with simulation, computer vision, control and test engineers to ensure that the scenes created are high quality and can enable the faithful reproduction of autopilot behavior in simulation.

(...)

As a Software Engineer, Embedded Framework within the Autopilot group, you will have the opportunity to apply your technical skills on the development of the embedded software stack of Tesla’s Autopilot. You will work on the Framework & Architecture aspects that tie all components of the Autopilot SW stack together, and work on improving the overall performance of the stack.

(...)

Responsibilities:
  • Work with graphics engineers and artists to understand the requirements for asset creation and scene development for simulation.
  • Commission and manage artist subcontractors to fulfill simulator scene creation requirements.
  • Track project progress and work with all parties to ensure work packages are completed on time.
  • Maintain awareness of team-wide art and development issues.
  • Maintain awareness of the high-level goals of the autopilot program.
(...)
  • Work with technical artists and engineers in the development and streamlining of tools and processes.
  • Keep abreast of advanced techniques which could be used to improve the visual quality or development processes of the simulator.
(...)
  • Enhancing and maintaining the graphics of 3D engine for autopilot simulation
  • Responsible for performance of features
  • Responsible for tools that go along with features; ensure they are usable and appropriate for artists, simulations, and the engine
  • Be forward thinking keeping up to date on current techniques, research, graphics data, hardware, etc.
(...)
  • You will develop, debug and maintain the real-time C++ Framework that ties all the software components together;
  • You will apply your Software Architecture skills to design consistent API’s, work on real-time challenges with inter-process communication, and advocate for best coding practices amongst the group;
  • You will work with the Computer Vision and Algorithms teams, understand their requirements and translate them into robust, performant software frameworks;
  • You will improve the overall stack performance, and reduce resources consumption;

So what do you guys think?

What are Tesla's advantages and disadvantages, and how important is this stuff?

Very good question. Actually that's exactly what I hope people will help shed light on in here

I always assumed the FSD video was based on Nvidia code to some extent, but of course unknown really...

They did have that close Nvidia collaboration and Nvidia had been working on self-driving for a while now...

Model X mule(s) show signs of nVidia Tegra X1 Drive PX platform - no rear mirror!

...do note the interior camera on this 2015 image I posted on TMC back then... ;)

I can't even imagine how the dynamics of that relationship work. Tesla hasn't even implemented a solution based on Nvidia's offerings and they're already talking about ditching them for a chip that doesn't even exist yet from AMD.

I don't get it, but then again I don't even have a name yet for my car company :(

It's really too bad that Rockstar pulled the plug on this.

DeepDrive
Yeah, there was some discussion in Open AI because the released code was sudden all pulled and people were hoping it can return after working things out with Rockstar. Unfortunately, reading that post it seems like that part is dead.

Here's a whole article on Rockstar taking down various self-driving car projects using its engine:
Grand Theft Auto V: The Rise And Fall Of The DIY Self-Driving Car Lab

This one still seems to be alive though:
GitHub - ai-tor/DeepGTAV: A plugin for GTAV that transforms it into a vision-based self-driving car research environment.
