More like 1 per 100 million miles in the US. And remember that's all cars. I'm sure it would be significantly lower if you consider only late model cars with modern safety features.

Obviously, a lot of people still die in traffic accidents. But the bar is actually still fairly high for automated systems. I also suspect (though I don't have the numbers) that even if automation were just for highway driving that would, by itself, significantly reduce the fatalities.
