But if it's just a sensor, couldn't it be possible that sensor generates an erroneous signal such that it tells the car to accelerate when nobody actually pressed it?
- AlotOfReading 4y agoAcceleration pedal sensors are ASIL D and by ISO 26262 should have a probability of failure per operational hour of <10^-8. So yes, but it should be incredibly unlikely for sensor failures to occur and there's a very thick document somewhere inside Tesla detailing all the considered failure modes and how they've addressed them.

Maybe not all of them are like that, but I remember AvE (the YouTube channel) having to replace the pedal sensor on one of his cars a number of years ago and he talked about how they worked.
