这确实是在把技术提升到下一个层次，嗯，人们当然能够猜到，呃，我们要发布双电机Model S，但，嗯，他们今晚将了解到的是，它究竟有多大的改进。说到你不到，什么，10天前发出的那条推文，你发出了这条推文，呃，对于互联网基本上准确猜中了你将要发布什么，你感到惊讶吗？嗯，你知道，我认为现在互联网非常善于破解秘密，所以，就像，再也没有隐私了，嗯，但我认为我们还是让几个重要细节保留了一点惊喜，是的。呃，而你的股票上涨了，埃隆，大约8 n%，仅仅基于那条推文，你的市值因此增加了约30亿美元。

这，这令你惊讶吗？嗯，是的，我的意思是，仅仅基于一条推文就发生这种事，似乎不太可能，但，嗯，我，我不知道，也许我，我不知道，是的，也许这令人惊讶。嗯，我其实不太关注股价，我，你知道，嗯，因为我认为有时候股价会出于随机原因而波动，而且，嗯，你知道，如果它最终成了一个情绪晴雨表，那么，你知道，这样的生活并不快乐。嗯，因为几周前你自己曾说，听着，你认为股价有点高，之后它下跌了约10%，那么你仍然认为股价有点高吗？嗯，这取决于人们如何，呃，如果某人长期持有这只股票，我认为，呃，从长期来看，它会大幅升值，嗯，你知道。

短期内很难预测这些波动，嗯，但对于一家去年营收只有几十亿美元的公司来说，市值达到300多亿美元，你知道，似乎确实偏高，嗯，我认为那，呃，我认为互联网上肯定有很多很多人这样说，而且，你知道。那么你对自己的股票仍然是这种感觉吗？嗯，不，我的意思是，我，我只是，我觉得它，嗯，它，它，它总是很难预测短期波动，嗯，所以如果有人长期持有这只股票，我，我认为他们不应该卖出股票，我认为它会升值，最终会远高于今天的水平，嗯，但就短期波动而言，呃，那是无法判断的。现在我们来逐一介绍。

Model D的，呃，各项功能，基本上稍后再说，但我对在Model S中配备自动驾驶仪所涉及的法律问题感兴趣，对吧？嗯，埃隆，如果汽车确实发生碰撞，会怎么样？汽车处于自动驾驶仪模式时，谁来负责？是的，所以我认为，对我们来说，区分自动驾驶，嗯，与自动驾驶仪非常重要。自动驾驶仪是飞机上配备的东西，呃，例如，我们使用了他们在飞机上使用的同一个术语，在那里仍然预期会有一名飞行员，所以，所以如果，如果，飞行员有责任确保自动驾驶仪在做正确的事，嗯，它，它不是，我们还没有达到你可以入睡、然后在目的地醒来的阶段，嗯，呃，如果我们把它称为。

自动驾驶，而不是自动驾驶仪，如果，如果是那种情况。对，对，嗯，但我们正在做的是让驾驶汽车变得容易得多，呃，也舒适得多，嗯，并整合，呃，大量主动安全功能，所以汽车将，嗯，保持在自己的车道内，将自动损坏，将与其他汽车保持距离，呃，将，呃，避开高速公路护栏之类的东西和其他障碍物，嗯，但这仍然没有回答那个问题，埃隆，也就是说，假设它处于自动驾驶仪模式，所以它不是自动驾驶，呃，但如果它处于自动驾驶仪模式，而驾驶员说，嘿，你知道，它本来应该替我变道，结果却撞上了这道护栏，我希望，你知道，我希望Tesla对此负责。是的，嗯，我认为我们会非常明确地告诉客户，责任。

仍由驾驶员承担。好的，嗯，我们并没有声称汽车能够在没有驾驶员监督的情况下行驶，嗯，那，那会在未来某个时候成为现实，比如也许从现在起5年或6年，我认为我们将能够实现真正的自动驾驶，届时你真的可以坐进车里、睡着，然后在目的地醒来，嗯，但要做到这一点，你必须拥有完全冗余的系统，一切都必须是冗余的，这样任何一个系统制动都不会导致事故，嗯，而且你还必须通过，你知道，数百万英里的驾驶来证明这一点，然后，然后当然，然后我们必须向监管机构证明这一点，让他们相信它是安全的，所以我认为，从这个时间点来看。

真正的自动，呃，驾驶成为可能，我，我现在认为可能会在5年或6年的时间范围内实现。嗯，不过你以前说过，5到6年。是的，嗯，几年前我认为更像是10年，但根据我看到的改进速度，呃，以及我们正在取得的进展，我认为我们可能能够在5年或6年内做到，嗯，然后，但是，但是此后可能仍然需要2年或3年，监管，监管机构才会批准，因为我想确保它确实，嗯，比人类驾驶安全得多。完全自动驾驶的标准将远高于对人的标准，对吧，嗯，因为如果只是相当，那还不够。完全没有变化。

电池，对吧？你们在电池方面所做的事情以及你们如何，你们如何，好的，完全没有变化，但考虑到其中一些改进，续航里程会不会发生任何变化？是的，所以，呃，我们采用双电机的方式，实际上能够提高续航里程，因为我们可以更充分地平衡电机的效率，嗯，所以如果你只有1台电机，它总是，呃，处于某条特定的功率与效率曲线上，但如果你有2台电机，就可以在它们之间进行优化，嗯，并且实际上让，呃，让电机有更多时间运行在它们，它们效率更高的区间，最终结果是，仅仅通过改用双电机，我们就能把高速公路续航里程增加10英里，而在其他所有全轮驱动系统中，呃，你。

你会损失续航里程，这时你却获得了续航里程。

it's really taking the technology to the next level um people were able to guess of course that uh we're unveiling the dual motor Model S but um what what they'll learn uh tonight is just how much of improvement it is this whole tweet that you sent out less than what 10 days ago you sent this tweet out uh were you surprised by how the internet pretty much got it right with what you were going to unveil um you know I think the internet is very good at figuring out Secrets at this point so like there's no privacy anymore um but I think we were able to keep a few of the the the important details a little bit of a surprise yes uh and your stock went up Elon by something like8 n% just based on that tweet alone you earned about $3 billion in market cap on that

is that is that a surprise to you um yes I mean that that seems like an unlikely thing to happen just based on a tweet but um I I don't know maybe I I don't know yeah maybe it's surprising um I I don't really follow the stock that much I'm you know um because I think sometimes the stock moves for random reasons and um you know if that ends up being a mood barometer then it's you know it's not a happy life well because a few weeks ago you had said yourself look you thought the stock was a little bit high and it then fell about 10% after that so do you still think the stock is a little high well it depends on how people uh if somebody's a long-term holder of the stock I think uh there's a lot of appreciation uh that will occur in the long term um you know

in the short term it's difficult to predict these fluctuations um but it does seem as though you know for a company that had a few billion dollars in Revenue last year to have a 30 plus billion doll market cap is on the high side um and I think that's uh I think certainly lot lots of people on the internet who who say that and you know so you still feel that way then about your stock um no I mean I I just I feel like it's um it's it's it's always difficult to predict the short-term fluctuations um so if someone a long-term holder of the stock I I don't think they should sell the stock I think it will appreciate and ultimately be much higher than it is today um but in terms of short-term fluctuations uh it's that that's impossible to say now we'll go through

the features of uh of the model D essentially in a moment but I'm interested about the legal implications of having autopilot in the Model S's right um what happens Elon if the car does in fact crash who is going to be responsible when that car is on autopilot yeah so I think it's important for us to differentiate autonomous driving um versus autopilot autopilot is what they have an airplanes uh for example we we use the same term that they use in airplanes where there's still an expectation that there'll be a pilot so the so if if the the onus is on the pilot to make sure that the autopilot is doing the right thing um it's it's not we're not yet at the stage where uh you can go to sleep and wake up at your destination um uh if we would have called it

autonomous instead of autopilot if if that was the case right right um but what what we are doing is making it a lot uh easier and more comfortable to drive the car um and incorporating uh a lot of active safety features so the car will um stay in its Lane will automatically break will maintain a distance to other cars uh will uh avoid like Highway barriers and other obstacles um but that doesn't still address the question though Elon which is let's say it's on autopilot so it's not autonomous uh but if it's on a autopilot and a driver says hey you know this was supposed to change lanes for me and instead it hit this barrier I want you know I want Tesla to be responsible for this yeah um I think we're going to be quite clear with customers that the responsibility

remains with the driver okay um we're not asserting that the car is capable of driving um in the absence of driver oversight um that that will be the case in at some point in the future like maybe five or six years from now I think we'll be able to achieve true autonomous driving where you could literally get in the car go to sleep and wake up at your destination um but in order to do that you have to have fully redundant systems everything's got to be redundant so that any one system braking does not result in an accident um and you also have to prove that out over you know millions of miles of driving and then and then of course the then we have to prove that to The Regulators to convince them that it's safe and and so I think from the point of which

true autonomous uh driving is as possible which which I I now think is probably in the five or six year time frame um you said that before though five to six years yeah um if a couple years ago I thought it was more like 10 years but based on the rate of improvement uh that I'm seeing and the progress we're making I think we'll probably able to do it in five or six years um and then but but it's probably still going to take two or 3 years after that before The regul Regulators approve it because I want to make sure that it's truly um a lot safer than driving with a person this the standard for fully autonomous driving is going to be much greater than for a person right um cuz if it's just equivalent that wouldn't be enough there's no change at all in

the battery right there's no change at all in what you're doing with and how you're how you're okay but is there going to be a change at all in the driving range given some of these improvements yeah so uh the way we're doing dual motor uh it actually enables a range increase because we're able to balance the efficiency of the motors a lot more um so if you just have one motor it's always uh on on a particular power versus efficiency curve but if you got two Motors you can optimize between them um and actually have uh have the motors operate in their their more efficient regime more of the time and the net result is that we're able to get 10 miles more Highway range just just by going to dual motors whereas in every other all-wheel drive system uh you

you lose range this when you gain it
