Do you work for Tesla FSD? That's exactly their stance. If I'm still dependent, then it doesn't do what it says on the tin. I want my money back.

That depends on how they fail. If they trigger on false positives, that's money wasted on lost time and damaged equipment.

On the flip side, if they fail a real case, it may well be because they engendered a false sense of safety, a bit like a sharp knife being safer than a dull one.

People exhibit different behaviors of risk taking when they know there are safety systems in place to protect them.
