It doesn't really matter whether autonomous cars crash less than human drivers. A computer can never be punished, so a computer must never be allowed to kill any humans.
Suppose human drivers were killing 1 person every 100 miles driven, and software was killing 1 person every 10 billion miles driven. We should just accept that the human population will be decimated each day for accountability reasons?
I do think that currently we're at the stage where Waymo is trying to convince most of the world of the _quality_ of its offering, so for the moment, things are well aligned.
But in 5 years if there are multiple self-driving offerings competing on things like price, door-to-door time, OPEX (e.g. does a camera-only system with no moving parts need less skilled maintenance?), then someone may try to be the cheap but good enough self-driving service that cuts corners -- and we should want some execs to actually go to prison rather than just some cost-of-doing-business fines.
Where do you live that humans are punished for "accidents"? You can run someone over in America and it's basically an "oopsie, do better next time!"
* 12 deaths per 100,000 per year, but 4 people go to jail for it
* 2 deaths per 100,000 per year, but no one goes to jail
Because apparently going to jail is important for some reason?
Honestly, choosing jail is somewhat dystopian IMO
How does punishing someone make crashes better? I would rather have fewer crashes because of a system that can't be punished than more crashes with punishment.
Being able to punish someone doesn't change the fact that a crash happened and it doesn't change the fact that someone died. There is a difference between punishment and justice, there is rarely ever perfect justice in life.
The best we can do is mitigate harms as much as possible, and it seems self-driving might be the best mitigation of traffic accidents compared to human drivers.
