These aren't hard questions in the long term though.

Non responsive passenger->follow protocol that emergency services prefers (or even legally requires).

Fist fight->stop car, inform passengers that car won't transport them further.

Rape->turn over recordings of vehicle interior to police.

I suppose for the last one you have to take it as a given that they are making such recordings (probably on a rolling basis), but there you go.

It's not like these situations are any thornier because an automated system is involved. Passed out person is better off with monitoring (at least in health terms), fist fight without car, same difference, rape without monitoring, no video evidence.
