> ... it's not acceptable for automation to fail danger, it must fail safe... The scary thing is, by definition of what is being automated there can be no fail-safe. The only "safe" is to stop the car. If the car detected it was going to crash, then it wouldn't have had the failure in the first place. By the time the failure might be detected, it is already too late for "safe".
