In any case, the SPEED limit for autopilot is still there. AP won't go over 35 in a residential area like that.
TACC has no such limit- it'll let you set 90 on a local road even if it has no speed limit info.
Hence why I pointed out the speed is a reason it
could not be AP but
could be TACC alone
Knightshade. I'm one of those who like the skepticism you often provide here. I agree there is often too much consensus and 'Tesla is never wrong' sentiment here.
That said. While we don't know what happened here yet the only reason anyone is blaming this on AP is that it's a Tesla. There is zero possibility that any police or any other rescue personnel on site could determine this. It's all based on 'there was no one in the driver seat'.
I don't disagree with any of that.
And I'm among those here pointing out it was almost for certain
not on AP
(even if one particular user grinding an axe keeps wanting to suggest otherwise)
So what is the likeliest scenario here?
There's basically 2 at least somewhat likely scenarios-
1) They turned on TACC, thinking it was AP.
That explains why it would engage on an unmarked road, why it would keep driving straight instead of taking the turn, and why it would accelerate well past residential street speed limits AP would impose.
2) Certainly it's POSSIBLE there was a 3rd person driving who ran as well-- though the crash was bad enough to kill 2 other people in the car in one of the safest cars in the world- so it'd be somewhat remarkable it killed those 2 but the driver was so injury free he was able to exit the vehicle and flee. But that's the other "likely" possibility.
AP isn't involved in either scenario though.
Unfortunately, with the S having no interior cam, and the fire being so severe there'd be a massive loss of physical evidence (say, finding a 3rd persons blood, or blood on the drivers seat inconsistent with passenger position), there's going to be some evidence that'd make determining what happened harder to do.
Ideally some data auto uploaded to Tesla on the crash, that can at least establish last hands on wheel detection and state of TACC (I don't know if a crash dump reports seat sensor data- obviously THAT would be super useful to know...maybe
@verygreen knows)
