This is stupid. Teslas can park themselves, they're not just on rails. It should be pulling over and putting the flashers on if a driver is unresponsive.
That being said, the driver knew this behavior, acted with wanton disregard for safe driving practices, and so the incident is the driver's fault and they should be held responsible for their actions. It's not the courts job to legislate.
It's actually the NTSB's job to regulate car safety so if they don't already have it congress needs to grant them the authority to regulate what AI behavior is acceptable/define safeguards against misbehaving AI.
But you're right, and the management who kept ignoring problems is going to be tried here. It just so happens that the producer was also an actor and happened to be the one given a bad prop. Alec was the manager of everyone: he hired people, and decided they were doing a good enough job. After employees complained about safety problems, he ignored them. After people QUIT over those safety problems, he continued ignoring them. Alec the producer is the one on trial, not Alec the actor.
