> That does leave you all sorts of room to come up with realistic trolley problems

But all require a human (or malicious) driver on one hand. The more rule-following AVs on the road, the fewer the opportunities for such trolley problems.

And I'd still argue that debating these ex ante is, while philosophically fascinating, not a practical discussion. I'm not seeing a case where one would code anything further than collision avoidance and e.g. pre-activating restraints.
