Maybe (and imho that's not a given), but to save lives you don't need to wait for AVs. There are already solutions for that. Look at Helsinki. Zero road deaths, but no AVs. Slowing down cars is probably the most effective tool but there's a lot more that can be done now.
And don't forget, Waymo's goal is not to save lives but to make money. I wouldn't bet on them.
