People have been trying the driver-monitoring-as-a-shortcut approach for years now. It turns out that effective driver monitoring is extremely difficult, so the typical result is that you end up with the worst of both worlds: A system designed under the assumption that there's a human backup and a human that's not able to react quickly enough to prevent accidents.

It's not clear how to fix this, because the human can appear completely fine by all observable metrics even when they aren't, and vice versa to a lesser extent. This problem also gets worse the better your autonomous performance is.

That's why virtually every safety expert in the field is fairly critical of these sorts of systems.

You missed another quality of the worst world: driver monitoring that disengages even for a perfectly attentive driver. That’s about where Tesla is now.
