And yet the humans managed.

Even at a normal four-way stop with stop signs people sometimes blow through it. The Waymo has to handle it.

That’s part of driving.

It can creep through at 3 miles an hour if it thinks that’s what’s safe. All it has to do is get out of the intersection.

The outrage people would rightly have at Waymo allowing a number of its vehicles to blow the lights would be huge. People running blacked out lights is unacceptable.

Who said “blow through”?

Waymos know how to handle 4 way stops.

You're anthropomorphizing. Waymos "know" how to handle the 4-way stops that they've been trained to handle.
