There are individual intersections in the US that have that many vehicles pass each day. I haven't seen estimates on number of specifically vehicle-pedestrian interactions, but 5 9s is nowhere nearly safe enough.

How many times does a car see this particular interaction, though?

It needs to handle new interactions too. Humans aren't predictable

That's also a factor. I've been driving for decades now, yet still need to handle surprisingly novel situations now and then.
