No, the statistics I've seen haven't really been useful.

It's typically comparing cars in whatever autonomous modes vs all cars operating within a country/state. But the autonomous modes don't operate in all conditions, so it's not a good comparison.

There's concern about making sure the control group is appropriate too, comparing against a representative subset of the population is important.

I think there's some reasonable data for automatic emergency braking, in that I think I've seen it compared as just cars with aeb equipped vs cars without, number/severity of injuries for all collisions and there's enough data to show a difference.
