That's why if you're involved in a Tesla accident, even a fatal one, Tesla will have no hesitation holding a press conference, pulling vehicle telemetry, to make sure that (rightly or wrongly) blame goes to you as the driver and not Tesla.
They'll make statements like "Autopilot wasn't to blame here. The vehicle had warned the driver of his inattentiveness", and the Tesla fans will nod their heads, reassured.
What will later come out will be that Autopilot was active, and that while a driver attention (steering wheel) warning had occurred on the fateful trip, it had happened ONCE, and that that one time was EIGHTEEN MINUTES prior to the collision.
But there won't be a press conference to correct those details.
