They had one for every route they completed.

And one by one, they pick off the Larry 1K routes.

And they think this is going to take them about two years when they start out.

And they do it in a little bit more than a year.

Nearly twice as fast as they had expected.

By fall of 2010, they're done.

They throw each other in the pool.

They celebrate, and then they're not entirely sure what to do next.

The team had pulled off a kind of miracle in a year.

A driverless car with human supervision, with lots of human coding, but still a driverless car successfully navigating some very tricky roads in California.

They'd done this safely.

They'd done it quickly.

And now things would begin to wobble.

Competition would arrive.

The team itself would begin to schism.

And one member, a person who believed the team was moving too slowly, would actually take matters into his own hands in a particularly extreme way.

After the break, mutiny.

Hey there, Stephen Dubner.

That, again, is PJ Vogt.
