Amazing! And the most amazing thing is that only Tesla has figured out that you just pump miles into machine learning and get a self-driving car out! All those idiots investing billions in developing this technology; if only they were as smart as Elon. Well I guess the cat is out of the bag now, right? And we're going to see Waymo do a complete about-face, ditch the LAME lidar, replace their nice cameras with cell phone cameras, and just go for MOAR MILEZ. I mean, Tesla just showed everybody how simple this is, right? You'd have to be an idiot not to get it.
No, just pumping a ton of data into machine learning blindly, will not just magically give you a self-driving car. The key is getting the right data, using that data correctly and what you do with the machine learning on the output end. Machine learning is kinda like sex, "it's not the size that matters, it's how you use it."
But the big data that Tesla has access to, is certainly helpful towards developing a self-driving car. As Tesla explained during Autonomy Investor Day, there are different helpful ways that they can leverage the big fleet. For example, they can collect very specific real world data like cars with bicycles on the rack and use that data to train the machine. Or, when Tesla has software that they think that can handle a specific situation, they can upload it into a lot of cars in "shadow mode" and collect feedback to see how it would perform in the real world. You can do these things with simulations of course, but having a large fleet of cars, means that you can do it in the real world, in real world conditions and you can do it faster and on a bigger scale. Again, that's going to be helpful.
So, Tesla's big fleet does not guarantee full self-driving but it is a very helpful tool.
