| 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. |
目前为止我还没有成功,所以这只是一个进度报告, 而更主要的是,我会介绍一些关于无人驾驶汽车的事。 |

| 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. |

| 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. |
不可思议的事发生了: 它成为DARPA无人驾驶汽车大赛中 第一部回来了的汽车－－ 这也为斯坦福赢得了两百万美元的奖金。 |
|
unimaginable:adj.不可思议的;难以想像的;
|
| Yet I still hadn't saved a single life. |
但我还没挽救任何生命。 |
| Since, our work has focused on building driving cars that can drive anywhere by themselves -- any street in California. |
自那时起,我们便开始专注于 建造一部能在任何地方 加州的任何一条街道, 自己驾驶的汽车。 |
| We've driven 140,000 miles. |
我们已经让它成功行驶了14万英里。 |
| Our cars have sensors by which they magically can see everything around them and make decisions about every aspect of driving. |
通过传感器 我们的汽车可以神奇的看到 它周围的一切事物 并据此对如何驾驶 做出判断。 |
