That is a very poor analogy. Airbags have only killed a few hundred people and in many of those cases the manufacturer was still not liable because of human error (victim was not wearing a seatbelt, was a child improperly seated in the front, etc.) The manufacturer liability exposure for fully autonomous driving is literally several orders of magnitude greater than for airbags.
