No there isn't, but with the average new car price increasing every year and now is ~$37k, I think most recently new cars have some or all of these systems, and every year more old cars get scrapped.
So my assumption that each year the US car fleet in general is safer than the previous is probably correct, no? And yet traffic fatalities are going up?
My guess is that these nanny systems allow more distracted driving which is the real problem. A set of human eyes attached to a reasonably attentive brain, with some training, and many hundreds of hours experience is still much more capable to avoid an accident than a computer. The trick is to keep the human watching the road and driving with good habits.
I'm sure eventually full self driving cars will be as safe as human piloted airline travel, but probably will require real time communications between vehicles and a virtual "slot car" system.
