This comment takes as fact a claim made by the police, which might be wrong, either by error or purpose.
One thing is for certain though, the police’s initial investigation was criminal. That is to say it was to establish the fact of who was the driver, etc. It was totally separate from the civil litigation that later established Tesla to be at 30% fault for the wreck using computer records establishing that ADAS was engaged.
Leaving Tesla out of it, suppose there was some other automaker with some other problem. A cop comes to them and says “what do I need to ask you to establish the facts about an accident?” Since when do police just accept “oh, the potentially adversarial lawyer gave me advice on what they can tell me without getting a subpoena. Guess that’s all I can do?” That’s absurd.

Should companies be intentionally misleading to law enforcement about what data they have on fatal accidents like Tesla?
