Another thing that gets missed is this: With self-driving cars every single fatal accident will be investigated, and the result of that investigation will be used to improve the software on all cars in the network.

In this way the rate at which cars kill people will decline, similar to the systematic decline in airplane deaths over the years.

So maybe it's worth initially accepting a self-driving fatality rate that is slightly above the human-driving rate?
