Who's Liable for George Hotz's Self-Driving Software?

Self-driving-cars are notoriously difficult to test for safety. Hotz writes in an email, "It's not my code, I did not release it"--Comma.ai Inc. "released and maintains it." Most legal experts that spoke with IEEE Spectrum--and Hotz himself--believe that if you use the company's code and something goes wrong, then it isn't liable for damages. But Consumer Watchdog advocate John Simpson doesn't believe this is fair.
