US road fatalities. This is because NHTSA catalogs every one of them and the circumstances leading up to them. This product is called the FARS.

You're assuming they'll use the automation. Or you're presuming it will be forced on people. Which ignored motorcycles. Or bicycles. People use those.
> Deaths and injuries resulting from motor vehicle crashes are the leading cause of death for persons of every age from 3 through 33 (based on 2003 data).
I'd like to know where you got that statistic from. In the US, it is not likely to be true. Accidental self inflicted injury, a separate category, is often the most common until Heart Disease and Cancer become factors.
The reason to use the US is because it is a developed country, a wide variety of different states and road conditions, and it has a single reporting agency covering it. Presuming that automated vehicles are going to lead to major improvements outside of developed nations is a bit unfounded.
