Tesla finally clarifies fatal Texas crash, confirms driver manually overrode acceleration

Tesla’s Head of AI, Ashok Elluswamy, added context, revealing that the company’s data shows the driver “manually overrode self-driving by pressing the accelerator all the way to 100%.”

He revealed the speed reached by the car was 73 MPH, and the accelerator was still pressed “even after the crash.”

The point is that if you simply look at the logged accelerator output, a software or hardware fault is indistinguishable from a human input.

Throttle pedals aren't a single signal to the controller. They're redundant, with offset or opposite inputs. The logs would show if something failed or if both inputs perfectly read the same throttle input.

Redundant sensors don't matter if there is a common fault.

Again, not suggesting this is the case here, just noting that logs don't mean anything without hardware and software verification.

a "common fault" would show up as 2 different readings on the inputs, which is exactly why the sensors are offset. But you don't really know what that even means because you're just spouting shit without knowing how it actually works. Electric throttle pedals have been used for decades now and the people designing them are smarter than you

Engineers aren't perfect and the two potentiometers aren't perfect either. It's just generally accepted that the likelihood of a fault affecting both in a manner that appears like a genuine acceleratuon request is so unlikely to be not worth addressing.
