LeCun：驾驶数据数十亿小时仍无 L5 自动驾驶
We have billions of hours of training data for driving: video+sensor inputs together with steering wheel and pedal actions.
我们有数十亿小时的驾驶训练数据：视频+传感器输入，以及方向盘和踏板动作。 尽管如此，我们仍然没有 Level-5 自动驾驶汽车。 这不仅仅是运行时间的问题，而是数据需求和样本效率的问题。 （在你问之前先说：Tesla FSD 被评为 Level 2，Waymo 尽管使用了激光雷达和其他超人传感器，也只是 Level-4。它们所需的训练数据都远超 20 小时。）

We have billions of hours of training data for driving: video+sensor inputs together with steering wheel and pedal actions. Despite that, we still don't have Level-5 self-driving cars.
It not just about running time it's about data requirements and sample efficiency.
(Before you ask, Tesla FSD is rated Level 2, and Waymo is Level-4 despite using lidar and other superhuman sensors. They have both required way more than 20 hours of training data)
