I'm not sure your second point is as strong as you believe it to be. Do you have a specific example in mind? I think most vehicle problems that would require an emergency responder will have easy access to a tow service to deal with the car with or without a human being involved. It's not like just because a human is there that the problem is more easily solved. For minor-to-moderate accidents that just require a police report, things might get messy but that's an issue with the law, not necessarily something inherently wrong with the concept of self driving vehicles.
Also, your first point is on shaky ground, I think. I don't know why the metric is accidents with fatalities, but since that's what you used, what do you think having fewer humans involved does to the chance of killing a human?
I'm all for numbers being crunched, and to be clear (as you were, I think) the numbers are the real deciding metrics here, not thought experiments.
And I think it's 100% true that autonomous transportation doesn't have to be perfect, just better than humans. Not that you disagree with this, but it is probably what people are thinking when they say "humans do this too".
This conspiracy theory doesn't make much sense to me. If they wanted to they could have just gave him probation and sent him on his way, right? Why go through this convoluted path of charging him and convicting him, and let him go?
Am I misunderstanding you? It feels like I'm misunderstanding you.
