Tesla and Steam? It's coming and it sounds like it's progressing nicely with a demo to come soon to show it off.
Something that has been in the works for a while, and we already know their entertainment software uses Linux so it will use the Linux version of Steam. This will also include the Proton compatibility tool for running Windows games as well to enable plenty more gaming in your fancy Tesla.
We actually saw hints of this back in 2021, as Tesla were advertising for "Linux Game Development at Tesla" position which you can see via the Wayback Machine. This involved working with "Linux, Mesa, Vulkan, OpenGL, Proton/Lutris, Wine, etc." so it was pretty clear where they were going with it. Add to that Elon Musk said on Twitter in early 2022 that "We’re working through the general case of making Steam games work on a Tesla vs specific titles. Former is obviously where we should be long-term.".
Just recently on July 16, 2022 again on Twitter, Musk said: "We’re making progress with Steam integration. Demo probably next month.".
