So there's an interesting legal question here. If someone's drunk (i.e diminished reasoning) and steps into the car expecting that a feature named "full self driving" will safely drive them home, how is responsibility divided between the person who got drunk and the entity who created and named the "full self driving" feature? I don't think even a reasonable person could consistently conclude that "full self driving"…
If it's truly self driving then the passenger shouldn't be responsible at all. Would riders be responsible for taxi drivers?
If you get into a cab, and the driver is clearly drunk or exhibits violent behavior on the road, surely you have some responsibility to terminate your ride.
So if you get into a Tesla with it's wink-wink-nudge-nudge-named FSD, which warns you to be ready to take over, and you then note that the person being asked to take over is intoxicated... it seems like the responsibility is clearly on the operator.
But your standard - "it's truly self driving" - is a higher one. And I really don't know how to think about responsibility in that case, and it feels like a big problem. On one hand, it seems that, in the coming decades, we'll likely have actual full self-driving that operates in some situations in manners that are more safe than human drivers (especially people who are intoxicated, who also deserve a safe way home even in car-first hellscapes of urban planning).
On the other hand, we've seen how most of the USA has been terraformed to accommodate the product being hocked by the auto industry, and that this product has long had an undesirable role in population-level mortality rates (even without FSD!).
So yeah, I don't know.
It seems like micro-mobility solutions, and getting highway vehicles out of cities, give us a better outlook altogether anyway. Particularly if there is robust public medium- and long-haul public transit which can convey micro-mobility solutions to faraway lands.
