Elon Musk believes that Tesla has the "best real-world AI," which powers its self-driving tech.
Whistleblower Lukasz Krupski told BBC News that the Autopilot feature wasn't ready for public use.
"It affects all of us because we are essentially experiments in public roads," he told BBC News.
A lawyer representing Tesla told the newspaper that Krupski was a "disgruntled former employee," and said he abused his position to release the material.
Some documents leaked to The Handelsblatt had recorded accidents that occurred when using Tesla's Autopilot feature, first released in 2015.
