when you really shouldn't have been driving?

Maybe you're out on the road for a long day,

You were tired, but you felt you could drive a few more miles.

I've had less to drink than everybody else,

Or maybe your mind was just entirely elsewhere.

Now, in those situations, wouldn't it be great

that you could push, and the car would get you home safely?

Now, that's been the promise of the self-driving car,

the autonomous vehicle, and it's been the dream

since at least 1939, when General Motors showcased

this idea at their Futurama booth at the World's Fair.

that's always seemed about 20 years in the future.

Now, two weeks ago, that dream took a step forward,

when the state of Nevada granted Google's self-driving car

the very first license for an autonomous vehicle,

clearly establishing that it's legal for them

Now, California's considering similar legislation,

and this would make sure that the autonomous car

is not one of those things that has to stay in Vegas.

Now, in my lab at Stanford, we've been working on

autonomous cars too, but with a slightly different spin

on things. You see, we've been developing robotic race cars,

cars that can actually push themselves to the very limits

Now, why would we want to do such a thing?

Well, there's two really good reasons for this.

First, we believe that before people turn over control

to an autonomous car, that autonomous car should be

at least as good as the very best human drivers.

Now, if you're like me, and the other 70 percent of the population

who know that we are above-average drivers,

Just like race car drivers can use all of the friction

all of the car's capabilities to go as fast as possible,

we want to use all of those capabilities to avoid

but because you've hit an icy patch of road,

that is capable enough to avoid any accident

I must confess, there's kind of a third motivation as well.

although maybe not at the level that you're currently expecting.

One of the things that we've developed in the lab --

where maybe there's not a lot of competition.

But this is P1. It's an entirely student-built electric vehicle,

It can get sideways like a rally car driver,

We've also worked with Volkswagen Oracle,

on Shelley, an autonomous race car that has raced

at 150 miles an hour through the Bonneville Salt Flats,

gone around Thunderhill Raceway Park in the sun,

and navigated the 153 turns and 12.4 miles

I guess it goes without saying that we've had a lot of fun

But in fact, there's something else that we've developed

in the process of developing these autonomous cars.

We have developed a tremendous appreciation

for the capabilities of human race car drivers.

As we've looked at the question of how well do these cars perform,

we wanted to compare them to our human counterparts.

And we discovered their human counterparts are amazing.

we can take a mathematical model of a car,

and with some iteration, we can actually find
