演讲者强调，特斯拉目前正在以**前所未有的速度**在美国各地扩展其自动驾驶出租车服务。 一项重大进展，被强调为“一个重要的转折点”和“第三个重要信号”，即**特斯拉在迈阿密推出了其自动驾驶出租车服务，并且从第一天起就实现了完全无人监管运营**，这意味着没有监督人员在场。 演讲者断言，**在迈阿密实现无人监管运营的这种能力表明特斯拉完全可以在其他地方也做到同样的事情**。 预计**特斯拉的自动驾驶出租车服务迟早会在美国覆盖比Waymo更多的城市**，最终将数量**翻倍，然后翻三倍**，并持续快速增长。这种加速增长可以用“先慢后快，一蹴而就”这句俗语来概括。

The speaker emphasizes the **unprecedented pace** at which Tesla is currently scaling its RoboTaxi service throughout the United States. A major development, highlighted as a "big swinging moment" and a "third major signal," is **Tesla's launch of its RoboTaxi service in Miami with a fully unsupervised operation from day one**, meaning no supervisors were present. The speaker asserts that **this capability to launch unsupervised in Miami demonstrates Tesla can do the exact same thing elsewhere**. It is predicted to be **only a matter of time before Tesla's RoboTaxi service scales to more cities in the US than Waymo**, eventually **doubling, then tripling that number**, and continuing to grow rapidly. This accelerated growth is summarized by the saying, "Slowly and then all at once."
