All this simulation buys a single vehicle that drives better. That failure was a fleet-wide event (overloading the remote assistance humans).

That is, both are true: this high-fidelity simulation is valuable and it won't catch all failure modes. Or in other words, it's still on Waymo for failing during the power outage, but it's not uniquely on Waymo's simulation team.

They've also been seen driving directly into flood waters, with one driving through the middle of a flooded parking lot.
