  • 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.

  • (Applause)

As a boy,
