You could, you know, just Google it: https://waymo.com/safety/impact/. TLDR ~90% reduction of serious injury compared with human drivers.

Now, before you say this peer-reviewed paper is corporate propaganda, all self-driving companies are required by law to disclose accidents they are involved in, whether liable or not, in CA. You could access each raw accident report published by the CA DMV periodically and come up with your own statistics.
