> Yes, but accidental emergency breaking can cause just as bad of an accident as this, it all just depends on the scenario.

If Volvo's system is that dangerous, then it should not be on the road at all - but there is no evidence that it is, you are just making a speculative argument.

> They had hired a driver to sit behind the wheel to monitor the road and the car for exactly this reason.

That is no reason to disable a safety feature that would add safety in depth.

> The driver they hired decided to watch a movie on their phone instead of paying attention to the road.

That was a major error - a crime, in fact - but, unfortunately, also an entirely predictable scenario that cannot be dismissed on the grounds that dealing with it would make testing more difficult or expensive. So now we have three errors.
