Because for some reason Tesla is exempt from reporting specifics about their safety reporting. Can’t possibly imagine why…
The redactions have the note:
“[REDACTED, MAY CONTAIN CONFIDENTIAL BUSINESS INFORMATION]”
So any company has the option to redact information if they feel like it. Tesla has chosen to provide as little information as possible, claiming business secrecy, and no one can compel them otherwise.
A normal firm would have a heads up warning when requests for comment hit their media inboxes and internally could start collecting data and developing a response: thanks to Elon they don't. The story hits first and goes completely unchallenged until investigators get involved.
Regardless of what you think of Tesla or Musk, they repeatedly kick own goals on basic product brand management.
