That's not a good example. Courts move slow and that just barely happened and AFAIK is still being investigated (plus searching, the participants signed wavers -- though wavers don't give immunity legal negligence).

There's plenty of examples of companies being punished for negligence. It happens all the time when, say, their poorly constructed building collapses, cutting corners causes an oil spill in the Gulf of Mexico, they falsified their vehicle emissions reports, or when they abuse their market dominance.

Corporations totally do get away with a lot, but I don't see why you'd expect self driving cars to be a place where that would happen, especially since manually driven cars are already so regulated and require insurance. And everyone knows that driving is dangerous. Nobody is under any false impressions that self driving cars don't have at least some of that same danger. I mean, even if the AI was utterly perfect, they'd still need insurance to protect against cases that aren't the AI's fault.
