Well, if they caused you any specific loss nothing prevents you from suing them in civil court like in any other situation when somebody causes you a specific loss. That though is a completely different thing from criminal prosecution.
Waymo and specific people there responsible for that programming/bugs could probably be charged with criminal negligence by an enthusiastic prosecutor, yet haven't been. Why? Probably common sense. Like recognizing that there weren't criminal intent. And such situations is a price of progress. The same with protests. They weren't conspiring to block ambulances. And such situations is a price of freedom of protests and speech. Though if somebody dies that way, i think they would have a civil case against the protesters. The same way like affected people can have a civil case against Waymo in the situations mentioned above.
Neither of those are acceptable. Why would you think Waymo not following the law is somehow a justification for it to continue to put people’s lives at risk to enable protesters to do the same?
