Elon Musk says Tesla plans to “open source” the Model S and Model X, and he’s pointing to the original Roadster as the template.

The problem is Tesla’s Roadster release amounted to eight files on GitHub plus five document packages behind a login, with no open-source license attached to any of it.

Tesla has pushed the planned public demo of its next-generation Roadster to August or later, according to a report from The Information citing four people with knowledge of the program. It marks yet another delay for the vehicle first unveiled as a prototype nearly nine years ago.

The demo, expected to take place in Texas, is meant to showcase the SpaceX cold gas thruster system that Tesla claims will allow the Roadster to achieve extreme acceleration and even lift off the ground.
