If your brake lines burst, will you be able to coast safely to a stop?
Every piece of technology has a variety of failure modes, some more likely than others. FSD is not likely to take aim at a pedestrian and floor it, just like your brakes aren't likely to explode, and neither of you are irresponsible for making those assumptions
The difference is brake lines are inspected and understood by humans. Failure to reasonably maintain them is illegal.
No single human fully understands these AI models, and they can change daily. Yet Tesla is putting them in control of multi-ton vehicles and leaving all liability on humans with worse reaction time and little to no understanding of how it works or tends to go wrong.
What if it decides to short the batteries and set the car on fire? Can you stop it from doing that?
I think you are making scenarios that no reasonable person would assume. There is a difference between 'getting confused at an intersection and turning wrong' and 'actively trying to kill the occupant by accelerating at max speed while turning the steering'.
Battery and battery management is more straightforward. BYD has mastered it.
FSD is a blackbox. Even Tesla appears to be unable to prevent regressions. One of the most sophisticated companies in the world can't prevent regression in a safety critical software they frequently update. Let that sink in.
