Sebastian Thrun hjalp med at bygge Googles forbløffende førerløse bil, drevet af en meget personlig stræben efter, at redde liv og reducere trafikuheld. Overraskende video viser hvordan den DARPA Challenge-vindende bil kører gennem travl bytrafik uden nogen bag rettet og dramatiske billeder af testkørslen fra TED2011 demonstrerer hvor hurtigt bilen egentlig kan køre.

As a boy,

2000
Som en lille dreng,
00:17
I loved cars.
1
2000
2000
elskede jeg biler.
00:19
When I turned 18,
2
4000
2000
Da jeg blev 18,
00:21
I lost my best friend to a car accident.
3
6000
3000
mistede jeg min bedste ven i en bilulykke.
00:25
Like this.
4
10000
2000
Sådan der!
00:27
And then I decided I'd dedicate my life
5
12000
3000
Og da besluttede jeg, at jeg vil vi mit liv til,
00:30
to saving one million people
6
15000
2000
at redde en million mennesker
00:32
every year.
7
17000
2000
om året.
00:34
Now I haven't succeeded, so this is just a progress report,
8
19000
3000
Det er ikke lykkedes endnu, så det her er bare en forløbsrapport,
00:37
but I'm here to tell you a little bit about self-driving cars.
9
22000
3000
men jeg er her for, at fortælle jer lidt om selvkørende biler.
00:40
I saw the concept first
10
25000
2000
Jeg så det første koncept
00:42
in the DARPA Grand Challenges
11
27000
2000
i DARPA Grand Challenges,
00:44
where the U.S. government issued a prize
12
29000
2000
hvor den Amerikanske Stat uddelte en pris
00:46
to build a self-driving car that could navigate a desert.
13
31000
3000
til at bygge en selvkørende bil, der kunne navigere rundt i en ørken.
00:49
And even though a hundred teams were there,
14
34000
3000
Og på trods af, at der var hundrede hold der,
00:52
these cars went nowhere.
15
37000
3000
blev bilerne ikke til noget.
00:55
So we decided at Stanford to build a different self-driving car.
16
40000
3000
Så vi besluttede på Stanford, at bygge en anderledes selvkørende bil.
00:58
We built the hardware and the software.
17
43000
3000
Vi byggede hardwaren og softwaren.
01:01
We made it learn from us,
18
46000
2000
Vi fik den til at lære fra os
01:03
and we set it free in the desert.
19
48000
3000
og satte den fri i ørkenen.
01:06
And the unimaginable happened:
20
51000
2000
Og det ufattelige skete:
01:08
it became the first car
21
53000
2000
det blev den første bil
01:10
to ever return from a DARPA Grand Challenge,
22
55000
2000
til at vende tilbage fra en DARPA Grand Challenge
01:12
winning Stanford 2 million dollars.
23
57000
3000
hvilket resulterede i at Stanford vandt 2 millioner dollars.
01:17
Yet I still hadn't saved a single life.
24
62000
3000
Alligevel, har jeg stadig ikke reddet et eneste liv.
01:20
Since, our work has focused
25
65000
3000
Siden da, har vores arbejde været fokuseret omkring
01:23
on building driving cars
26
68000
2000
at bygge kørende biler,
01:25
that can drive anywhere by themselves --
27
70000
3000
som kan køre hvorsomhelst af dem selv;
01:28
any street in California.
28
73000
2000
enhver gade i Californien.
01:30
We've driven 140,000 miles.
29
75000
3000
Vi har kørt 225.308 km.
01:33
Our cars have sensors
30
78000
3000
Vores biler har sensorer
01:36
by which they magically can see
31
81000
3000
som gør, at de på magisk vis kan se,
01:39
everything around them
32
84000
2000
alt omkring dem
01:41
and make decisions
33
86000
2000
og tage beslutninger om
01:43
about every aspect of driving.
34
88000
3000
ethvert aspekt af kørsel.
01:46
It's the perfect driving mechanism.
35
91000
3000
Det er den perfekte køremekanisme.
01:49
We've driven in cities,
36
94000
2000
Vi har kørt i byer,
01:51
like in San Francisco here.
37
96000
2000
som her i San Francisco.
01:53
We've driven from San Francisco to Los Angeles on Highway 1.
38
98000
4000
Vi har kørt fra San Francisco til Los Angeles på Highway 1.
01:57
We've encountered joggers,
39
102000
2000
Vi stødte på joggere,
01:59
busy highways, toll booths,
40
104000
3000
travle hovedveje, betalingsveje
02:02
and this is without a person in the loop;
41
107000
2000
og dette uden en person i kabinen;
02:04
the car just drives itself.
42
109000
2000
bilen kører bare af sig selv.
02:06
In fact, while we drove 140,000 miles,
43
111000
3000
Faktisk, mens vi kørte 225.308 km.
02:09
people didn't even notice.
44
114000
3000
var der ingen der opdagede det.
02:12
Mountain roads,
45
117000
2000
Bjergveje,
02:14
day and night,
46
119000
3000
dag og nat
02:17
and even crooked Lombard Street
47
122000
3000
og endda krogede Lombard Street
02:20
in San Francisco.
48
125000
2000
i San Francisco.
02:22
(Laughter)
49
127000
2000
[Latter]
02:25
Sometimes our cars get so crazy,
50
130000
3000
Nogle gange bliver vores biler så skøre,
02:28
they even do little stunts.
51
133000
3000
at de laver små strunts.
02:32
(Video) Man: Oh, my God.
52
137000
2000
[Video] Mand: Åh, Gud!
02:36
What?
53
141000
2000
Hvad?
02:38
Second Man: It's driving itself.
54
143000
3000
Anden mand: den kører af sig selv.
02:42
Sebastian Thrun: Now I can't get my friend Harold back to life,
55
147000
3000
Sebastian Thrun: jeg kan ikke få min ven Harold tilbage i mit liv,
02:45
but I can do something for all the people who died.
56
150000
2000
men jeg kan gøre noget for alle de mennesker der døde.
02:47
Do you know that driving accidents
57
152000
3000
Vidste I, at færdselsuheld
02:50
are the number one cause of death for young people?
58
155000
3000
er den største dødsårsag blandt unge?
02:53
And do you realize that almost all of those
59
158000
3000
Og er I klar over, at næsten alle af disse
02:56
are due to human error
60
161000
3000
skyldes menneskelige fejl
02:59
and not machine error,
61
164000
2000
og ikke maskinelle fejl
03:01
and can therefore be prevented by machines?
62
166000
3000
og derfor kan forhindres af maskiner?
03:05
Do you realize
63
170000
2000
Er I klar over,
03:07
that we could change the capacity of highways
64
172000
3000
at vi kan ændre kapaciteten af hovedveje
03:10
by a factor of two or three
65
175000
3000
med to eller tre gange,
03:13
if we didn't rely on human precision
66
178000
2000
hvis vi ikke er afhængige af menneskelig præcision
03:15
on staying in the lane --
67
180000
2000
til at blive i banen -
03:17
improve body position
68
182000
2000
forbedre kropsposition
03:19
and therefore drive a little bit closer together
69
184000
2000
og derfor kører en smule tættere
03:21
on a little bit narrower lanes,
70
186000
2000
på lidt smallere baner
03:23
and do away with all traffic jams on highways?
71
188000
3000
og afskaffer trafikpropper på hovedveje?
03:28
Do you realize that you, TED users,
72
193000
3000
Er I klar over at I, TED-brugere,
03:31
spend an average
73
196000
2000
gennemsnitligt bruger
03:33
of 52 minutes per day
74
198000
2000
52 minutter om dagen
03:35
in traffic,
75
200000
2000
i trafikken;
03:37
wasting your time
76
202000
2000
spilder jeres tid
03:39
on your daily commute?
77
204000
3000
på jeres daglige pendling?
03:42
You could regain this time.
78
207000
2000
I kan genvinde denne tid.
03:44
This is four billion hours
79
209000
2000
Dette er fire milliarder spildte timer
03:46
wasted in this country alone.
80
211000
3000
i dette land alene.
03:49
And it's 2.4 billion gallons of gasoline wasted.
81
214000
4000
Og det er 9 milliarder spildte liter benzin.
03:53
Now I think there's a vision here, a new technology,
82
218000
3000
Se, jeg mener at der er en ny vision her; en ny teknologi,
03:56
and I'm really looking forward to a time
83
221000
2000
og jeg ser virkelig frem til en tid
03:58
when generations after us look back at us
84
223000
2000
hvor generationer efter os, ser tilbage på os
04:00
and say how ridiculous it was that humans were driving cars.
85
225000
3000
og taler om hvor latterligt det var, at mennesker kørte biler.
04:03
Thank you.
86
228000
2000
Tak skal I have.
04:05
(Applause)
