睡前一听 谷歌无人车

睡前一听

睡前一直是大家忽略的时间，躺在床上看或听些原版英语视频材料，不仅可以提高我们的听力和语感，还能增加表达的观点以及素材。

本公众号定期推送五分钟左右的TED演讲视频（来自全世界众多科学、设计、文学、音乐等领域的杰出人物，分享他们关于技术、社会、人的思考和探索）

视频长度：4分14秒

口音：美式英语

内容简述：来自2011年的视频，他想通过无人车（self-driving car）可以挽救更多的每年因车祸而丧生的人们。无人车可以间接的减少我们的拥堵时间，减少汽油浪费。

为了照顾更多用流量听的同学们，特此做出音频版，小编先是从外网下载视频，在转换格式，实属辛苦，如果大家喜欢，就多多转发哦，支持下小编！

泛听小建议：你不太累的话，可以点击视频后，放在床头，闭眼聆听一遍。接着再看一遍，验证下是否和你听到的大意吻合。

学习学的太累的话，就听着入睡吧，晚安，好梦。

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.

00:37

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.

01:54

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?

03:02

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.

03:50

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.
