They need to add radar back. Ability to "see" slow downs or stopped traffic even if your vision is obscured is a great benefit for self driving.

That's your opinion, but Tesla does not "need" to add anything from the point of view of actual Tesla customers! Tesla cars are selling faster than they can make them and adding a Radar will slow down the manufacturing, not make it faster.

  Tesla is currently being sued by actual customers based on this exact issue. They've promised FSD, and can't deliver it - especially without lidar.

They need LiDAR. The biggest problem for FSD is still around bounding box detection. I just don't believe that you can infer the dimensions of objects using stereoscopic images with a reliability that you need to make FSD work.

  How do our eyes work?

    By us constantly moving them around in three dimensions unlike a car. And also having a computer behind them that deeply understands what an object is, the forms it should take and what its expected behaviour should be. We don’t ever confuse billboards for real people.

        For looking forward Tesla's have three fixed cameras looking from the rear view mirror. All the other cameras do not have stereoscopic vision and are not looking forward. A camera looking out from a side pillar isn't helping gauge the distance to something far up the road. On top of that these cameras can't move, can't be re-aimed, and have generally far worse dynamic range than our eyes.

    Our eyes work in concert with a supercomputer accessing huge stores of contextual data (far eclipsing anything in a Tesla neural database) to understand and react to unique situations.
