I haven’t read the fine print but you can have ten seconds of warning without predicting complications ten seconds in advance.

That 10 seconds simply means that the car must handle any situation safely for at least that amount of time. In practice, this means decisions such as emergency braking and steering must be autonomous but possible more complex scenarios (e.g. moving for emergency vehicle on a tight street) can be delegated to a human (or the system can simply pull over and stop).

They disable the system in cases of rain but at least from the marketing and videos demonstrating it, there’s no prediction of complex scenarios like you described.

No, you are not understanding what I explained. There is a moving horizon of time during which the ten seconds is continually extended, and the system needs to draw the line somewhere. When does the final ten seconds before cutoff begin? Your examples don't explain this. This is not easy stuff to solve without some compromises.

If it’s limited on what roads it can run on the 10 second window makes perfect sense. Just enable when you’re entering an unsupported roadway.
