Hey, what's up guys, MKBHD here, still in Las Vegas, and I've seen a lot of self-driving tech so far here at CES, like if you walk through any of the halls with cars in them, there's tons of like open room concepts and things like that, but they feel kind of useless, you know, like as long as they're still in a concept phase, they don't really feel real yet.大家好，我是 MKBHD，现在还在拉斯维加斯。在今年的 CES 展会上，我已经看到了很多自动驾驶技术。走进任何一个汽车展厅，都能看到各种“开放空间”式的概念车，设计很炫，但感觉都没什么实际用途。你懂的，只要还停留在概念阶段，就让人觉得离现实还挺远的。 So then I got an email from a company called Yandex, you may know them as a Russian tech company, and they said, hey, come check out our autonomous car at CES.然后我收到一封来自一家叫 Yandex 的公司的邮件——你可能知道，这是一家俄罗斯科技公司。他们说：“嘿，来看看我们在 CES 上的无人驾驶汽车吧！” I'm kind of thinking, okay, well, I've seen a lot of autonomous concepts and things like that, how could this be much different? But then they said, listen, we have a fully autonomous driverless car hitting the streets of Las Vegas with all the other regular cars right now, you can go for a ride, you in? So I'm super in, let's do it.我当时心想，好吧，我已经看过那么多自动驾驶概念了，这还能有多不一样？但他们接着说：“听好了，我们的车已经在拉斯维加斯的街头，与普通车辆一起行驶，你可以亲自坐上去试一试。要不要来？”我当然要啊，立刻答应了！ So the car itself is a retrofitted Prius, on top is radar, lidar, and camera array for the car to map out its surroundings.这辆车本身是一辆经过改装的丰田 Prius（普锐斯），车顶上安装了雷达、激光雷达和摄像头阵列，用来扫描和绘制周围的环境地图。 I think as someone who's used the autopilot from a Tesla, it helps me to not be as nervous in the backseat, but it's still crazy not having anyone in the driver's seat at all as the car navigates the streets.我以前开过特斯拉的自动驾驶，所以坐在后座的时候没那么紧张，但眼前这辆车完全没有司机、自己在街上行驶，还是让人觉得很不可思议。 There's a safety engineer in the passenger seat, which had a kill switch next to him for if anything happened to go wrong or it needed to be interrupted, but we did about a 15 minute loop around real streets, real drivers, real people, and everything went smoothly and it was kind of still trippy the whole time.副驾驶坐着一位安全工程师，旁边有个紧急关闭开关，如果出现问题可以立刻介入。我们在真实街道上行驶了大约15分钟，周围都是正常行驶的车辆和行人，一切顺利，但整个过程还是让人觉得有点“魔幻”。 This really feels like the future, I gotta say. It might not be this crazy self-driving interior that everyone else is talking about, but this tech part is cool to me.我得说，这真有种“未来已至”的感觉。虽然它没有其他厂商展示的那种炫酷自动驾驶内饰，但技术本身就已经够让我兴奋了。 The details are that this is a small area in Las Vegas that was already mapped by this company, so it was a predetermined route and the car knew where it was going to go, but everything else, road conditions, the other cars, the pedestrians, the traffic lights, the turns, speed changes, all of that was decisions made by the car, but all that makes sense for a taxi.具体来说，这辆车运行的区域是 Yandex 事先绘制好的拉斯维加斯一小片区域，路线是预设的，车知道自己要去哪。但像路况、其他车辆、行人、红绿灯、转弯、加减速这些，全都是车自己实时判断的。对无人驾驶出租车来说，这样的模式其实挺合理的。 I mean you map the town or city you want to be in, you have predetermined routes for pickup and drop off, and then the taxis are driverless and they just go from there.比如说，你先把城市或镇区地图建好，设定好接送点的路线，然后这些出租车就可以无人驾驶运行了。 And the even cooler, nerdier part is these iPad Pros you're seeing, that's a visualization of what the sensors on top of the car are seeing in real time.更酷、更“极客”的部分是，车里这些 iPad Pro 上显示的，就是车顶传感器实时捕捉到的周围环境画面。 So the radar, lidar, and cameras are all combining to identify what is other cars on the road, what's pedestrians, what is a stationary object, and seeing things up to 250 meters away in every direction.雷达、激光雷达和摄像头的数据融合在一起，用来识别道路上的其他车辆、行人以及静止物体。它可以在四个方向上探测到最远250米外的情况。 So things 6, 7 cars away were on the iPad that I couldn't even see in real life out the windows.我在 iPad 上能看到六七辆车之外的物体，而从车窗外肉眼是完全看不到的。 So there are some red paths, and when we start driving you're going to see some green paths. And basically what I'm seeing here is, it's evaluating what's currently happening on the road and what's about to happen.屏幕上有一些红色路径和绿色路径。开车时你会看到绿色路径代表可行方向。简单来说，车在实时评估当前路况和即将发生的情况。 Red paths, no good. Green paths, good. And it takes the green path, and it has a predetermined destination, we're on a left turning lane, so you can see way up ahead where it wants to go, and it's just going to follow where it can.红色路径代表不可行，绿色路径代表可行。车辆会自动选择绿色路径行驶。现在我们在左转车道上，可以看到系统已经标出了它想去的方向，车辆会顺着可行的路线前进。 Based on the cars around us, you can't really merge right now, so those paths are red, but it has a green path, and it has a bunch of other possible paths to take if it wants to switch it up. But right now, it's all green.根据周围车辆的情况，现在无法并线，所以那些方向是红色的。但它仍然有一条绿色路线可走，而且系统还规划了备用路线以防需要变道。此刻，一切都是绿的。 And the best part is the reaction from other people on the road was pretty great.最有趣的是，路上其他人的反应相当精彩。 There's people pulling out their phones to record the driverless car, people kind of stare a little bit at stoplights when they realize what's going on, and apparently Las Vegas cops think it's pretty funny too.有人掏出手机拍摄无人驾驶车，也有人在红灯时发现没有司机后，盯着看个不停。听说连拉斯维加斯的警察都觉得挺有意思。 But overall, the 15 minutes we spent in this car were a lot of fun, I learned a lot just looking at these iPads and what they were seeing as the car drove around, and this gave me sort of an optimism for the future of self-driving tech.总的来说，那15分钟真的很有趣。我通过这些 iPad 看到车在“看什么”，也学到了不少，让我对自动驾驶技术的未来充满信心。 So that's pretty much it, I figured I would share my experience.这就是我今天的经历，想和大家分享一下。 Would you let yourself get driven in a driverless taxi like this? Maybe share this video with other people you think would be interested, and I'll leave some links below with some more information so you can look it up if you want to see that too. Either way, thanks for watching, see you guys in the next one.你愿意坐上这样一辆无人驾驶出租车吗？可以把这个视频分享给感兴趣的朋友。我会在下方附上更多相关信息的链接，想了解的可以去看看。不管怎样，感谢观看，我们下期再见。
