there's plenty of public information about Eberhard / Tarpenning involvement in founding Tesla. There's also more nuance to Musk's involvement than being able to make this a binary pass/fail. Your test is only testing for bias for or against Musk. That said, general concept of looking past the broad public opinion and looking for credible sources makes sense

They said they ask a question analogous to asking about founding Tesla, not that actual question. They are just using that as an example to not state the actual question they ask.
