It is only unsafe if the human operator lets it continue in unsafe situations. In a situation where it is taking a right turn at a red light, the only safety issue here would be the possibility of cosmic rays flipping enough bits in such a way that causes the software to instantly trigger full torque into another car, say a 1964 convertible mustang for maximum chance of fatally injuring the other humans. By your own argument all adaptive cruise control is unsafe. Maybe you think the manual and warnings given to the consumer qualify "defining any operational domain where it can operate safely", but it doesn't give an exhaustive list of "here's where you can safely operate this", it just says to not use it when it's unsafe to do so - it's always "drive safely and take control when necessary" because the scenarios are literally infinite.
