(gentle music) Elon's the iOS. By the way, he paved the way for all of us. - Right, it's the iOS, true. - I would not be doing comma AI today if it was not for those conversations with Elon and if it were not for him saying, I think he said, "Well, obviously, "we're not gonna use LiDAR, we use cameras.

"Humans use cameras." - So what do you think about that? How important is LiDAR? Everybody else on L5 is using LiDAR. What are your thoughts on his provocative statement that LiDAR is a crutch? - See, sometimes he'll say dumb things like the driver monitoring thing, but sometimes he'll say absolutely, completely, 100% obviously true things.

Of course, LiDAR is a crutch. It's not even a good crutch. You're not even using it, oh, they're using it for localization, which isn't good in the first place. If you have to localize your car to centimeters in order to drive, yeah, they're not-- - That's not driving. - Currently not doing much machine learning on top of LiDAR data, meaning like to help you in the task of, general task of perception.

- The main goal of those LiDARs on those cars, I think is actually localization more than perception, or at least that's what they use them for. - Yeah, that's true. - If you wanna localize to centimeters, you can't use GPS. The fanciest GPS in the world can't do it, especially if you're under tree cover and stuff.

With LiDAR, you can do this pretty easily. - So you really, they're not taking on, I mean, in some research, they're using it for perception, and they're certainly not, which is sad, they're not fusing it well with vision. - They do use it for perception. I'm not saying they don't use it for perception, but the thing that, they have vision-based and radar-based perception systems as well.

You could remove the LiDAR and keep around a lot of the dynamic object perception. You wanna get centimeter accurate localization, good luck doing that with anything else. (electronic whooshing) (electronic whooshing) (electronic whooshing) (electronic whooshing) (electronic whooshing)
