They would need to have more of them first for the data to actually be accurate at all. From what I could find, there have been no Waymo caused fatalities - two deaths caused by other drivers though - and four serious injuries, for roughly 220 million miles driven.
While you can then state that the rate of fatalities is 1 per 110 million miles, it’s not really useful in any way.
Fatalities and serious injuries sound like a far more important statistic to optimize for in terms of public safety.
