Tesla claims that Autopilot is 40% safer and even gets NHTSA to repeat that claim.
When asked to release the evidence that supports the claim Tesla claims they are a SPECIAL CASE!
The heavily redacted letter from Tesla to NHTSA is still viewable here
Interestingly - the full document that was on SCRIBD has been removed.
Tesla says that information about crashes and victims is not publicly available.
(most likely because Tesla has settled out of court and slapped them with Non Disclosure Agreements)
