From the newsroom of the Washington Post.

Hi, good afternoon.

This is Tulu O'Rourer-Nipo with the Washington Post.

Hi, this is Amy Britton calling you the post.

This is Peter J. Davidson from the Washington Post.

This is Post for Ports.

I'm Martin Powers.

It's Wednesday, November 27th.

Today, what self-driving cars can't see?

A screenwriter who left Hollywood to become a novelist

and a politician with a passion for turkey.

So let's say you take a self-driving car out of the city.

And suddenly it sees something furry and for-legged.

Well, the car has to really rapidly decide what that thing is.

You as an adult or even as a toddler,

you're going to see something about the way that animal moves

or about the shape that says,

oh, hey, that's a cow.

Or maybe you'll see antlers and you'll say, hey, that's a deer.

And you'll sort of adjust your expectation

or your movements accordingly.

Now it's the car that suddenly has to make all of this decision.
