This LIDAR wank annoys me.

If you can train a policy that drives well on cameras, you can get self-driving. If you can't, you're fucked, and no amount of extra sensors will save you.

Self-driving isn't a sensor problem. It always was, is, and always will be an AI problem.

No amount of LIDAR engineering will ever get you a LIDAR that outputs ground truth steering commands. The best you'll ever get is noisy depth estimate speckles that you'll have to massage with, guess what, AI, to get them to do anything of use.

Sensor suite choice is an aside. Camera only 360 coverage? Good enough to move on. The rest of the problem lies with AI.

Even the best AI can't drive without good sensors. Cameras have to guess distance and they fail when there is insufficient contrast, direct sunlight and so on. LiDARs don't have to guess distance.

AI + cameras have relevant limitations that LIDAR augmented suites don't. You can paint a photorealistic roadway onto a brick wall and AI + cameras will try to drive right through it, dubbed the "Wile E. Coyote" problem.

You are correct, but the problem is nobody at Tesla or any other self driving company for that matter knows what they are doing when it comes to AI

If you are doing end to end driving policy (i.e the wrong way of doing it), having lidar is important as a correction factor to the cameras.

Just don't drive up north in the snow and your good.

Source: trust me, bro? This statement has no factual basis. Calling the most common approach of all other self-driving developers except Tesla a wank also is no argument but hate only.
