The GP is right, the correct mental model is just frequency of accidents. There's a high chance the accident might not be caused by you, it could be that you're a well behaved pedestrian and you still get hit. Your own cognitive abilities and skills matter, but only so much.

Would you rather that the other driver is a person or an algorithm? What if automated driving causes few % less accidents than humans but there's no liability or accountability when it happens? What if algorithms cause more accidents but far less fatal ones? When is it the best time to deploy them at scale, to enable rapid improvements and a significantly safer roads one year down the road? Difficult questions.
