Elon Musk presents Tesla's argument for relying solely on cameras rather than LiDAR sensors for autonomous driving.

Tesla and Elon Musk outline why they believe cameras (vs lidar) are all that is needed for Full Self Driving during the Tesla Autonomy Day for Investors on April 22, 2019. Elon also touches on why they don't consider HD Maps and precision lane markings to be Elon Musk says lidar "is a fool’s errand" and that anyone using lidar is "doomed." He goes on to say that they are "expensive sensors that are unnecessary. It’s like having a whole bunch of expensive appendices. Like, one appendix is bad, well now you have a whole bunch of them, it’s ridiculous, you’ll see." There quite a bit of debate in the self-driving world whether lidar is truly required for Full Self-Driving capabilities on autonomous vehicles. Lidar provides very a very accurate, high precision depth map of the world around the car, but is currently still fairly expensive and also has challenges seeing through occlusions, like rain, snow and fog. Tesla's argument is that roads were built for human drivers with vision and that vision systems, such as cameras will do a better job traversing that environment than other sensors, reading all the vision queues meant for drivers, like road signs, etc. In addition, Tesla believes their vision system (plus radar) accurately handles depth sensing problems and that lidar is not needed for that function.

On “Waymo and Daimler Trucks partner on the development of fully autonomous trucks”

I think Elon Musk makes some good points why Lidar isn’t the best choice. link to this video Waymo taxi looks incredible but how can they scale it.

On “Waymo CEO dismisses Tesla self-driving plan: “This is not how it works””

Elon talked about LIDAR at the autonomy investor day. Basically he said that the Dragon spacecraft has LIDAR and he spearheaded that effort. He also said that LIDAR and cameras both use the same wavelength, if you are going to add a sensor it makes more sense to add one which is outside of the visible wavelength. Even though I know nothing about driverless cars, the reasoning from Elon makes sense. link to this video

On “Scenarios in which Tesla FSD Beta 9.0 fails”

…onsider Tesla an example to follow ;-) And do not think they are any closer to getting a working system. Some of the statements show at least a second level understanding of what is required. Sensors are a means to it. Its about situational awareness but also inference. "LIDAR is a fool’s errand… and anyone relying on LIDAR is doomed. — Elon Musk" link to this video…

On “On Self-driving, Waymo is playing chess while Tesla plays checkers”

Anyone who owns a Tesla and has used the new V12.3 understands why Elon is so bullish about the Robo-Taxi's. He's said they've internally seen a 5x-10x reduction in disengagements on 12.4 (already trained, out soon), and that 12.5 is even better. Their GPU stack by end of the year will also be 8x the size it was earlier this year. Combine all this together, and the "feedback loop" with millions of people using FSD, it's looking like the "vision only" strategy will work. My question is what happens to all other car markers if it turns out Elon and Andrej Karpathy's strategy ( link to this video ) is the correct one?
