I'm surprised that either:
1. Nobody at Waymo thought of this,
2. Somebody did think of it but it wasn't considered important enough to prioritize, or
3. They tried to prep the cars for this and yet they nonetheless failed so badly
Everyone should have understood that driving requires improvisation in the face of uncommon but inevitable bespoke challenges that this generation of AI is not suited for. Either because it's common sense or because so many people have been shouting it for so long.
Clearly cars can navigate themselves, it's the lack of remote ops that halted everything
Likely 2. Not something that will make it into in their kpis. No one is getting promoted for mitigating black swan events.
