Google's driverless car | Sebastian Thrun

As a boy,

I loved cars.

When I turned 18,

I lost my best friend to a car accident.

Like this.

And then I decided I'd dedicate my life

to saving one million people

every year.

Now I haven't succeeded, so this is just a progress report,

but I'm here to tell you a little bit about self-driving cars.

I saw the concept first

in the DARPA Grand Challenges

where the U.S. government issued a prize

to build a self-driving car that could navigate a desert.

And even though a hundred teams were there,

these cars went nowhere.

So we decided at Stanford to build a different self-driving car.

We built the hardware and the software.

We made it learn from us,

and we set it free in the desert.

And the unimaginable happened:

it became the first car

to ever return from a DARPA Grand Challenge,

winning Stanford 2 million dollars.

Yet I still hadn't saved a single life.

Since, our work has focused

on building driving cars

that can drive anywhere by themselves --

any street in California.

We've driven 140,000 miles.

Our cars have sensors

by which they magically can see

everything around them

and make decisions

about every aspect of driving.

It's the perfect driving mechanism.

We've driven in cities,

like in San Francisco here.

We've driven from San Francisco to Los Angeles on Highway 1.

We've encountered joggers,

busy highways, toll booths,

and this is without a person in the loop;

the car just drives itself.

In fact, while we drove 140,000 miles,

people didn't even notice.

Mountain roads,

day and night,

and even crooked Lombard Street

in San Francisco.

(Laughter)

Sometimes our cars get so crazy,

they even do little stunts.

(Video) Man: Oh, my God.

What?

Second Man: It's driving itself.

Sebastian Thrun: Now I can't get my friend Harold back to life,

but I can do something for all the people who died.

Do you know that driving accidents

are the number one cause of death for young people?

And do you realize that almost all of those

are due to human error

and not machine error,

and can therefore be prevented by machines?

Do you realize

that we could change the capacity of highways

by a factor of two or three

if we didn't rely on human precision

on staying in the lane --

improve body position

and therefore drive a little bit closer together

on a little bit narrower lanes,

and do away with all traffic jams on highways?

Do you realize that you, TED users,

spend an average

of 52 minutes per day

in traffic,

wasting your time

on your daily commute?

You could regain this time.

This is four billion hours

wasted in this country alone.

And it's 2.4 billion gallons of gasoline wasted.

Now I think there's a vision here, a new technology,

and I'm really looking forward to a time

when generations after us look back at us

and say how ridiculous it was that humans were driving cars.

Thank you.
