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?

Far more complex sensors than cameras attached to some of the most complicated and least understood processing systems running a general intelligence with millions and millions of years of training.

Also, when you're in the car, you probably move your head more than you realize. Moving your head around and looking around also gives you better understandings of distance. Far more than a couple of cameras feeding a few megapixel images into a ML model.

Why make the difficult task of self-driving any harder, by artificially limiting the sensors you use? Planes have rigid aluminum wings and jet engines instead of bone muscle and feathers.

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.

>By us constantly moving them around in three dimensions unlike a car.

Fair but to compensate the car has many more cameras than we do.

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.

Rather poorly, given the rate of traffic accidents by humans.

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.

> adding a Radar will slow down the manufacturing, not make it faster

Tesla told the FCC that it plans to market a new radar starting next month.

If this is true, why are they reportedly cutting production and offering incentives? If they were booked solid, no incentives would be needed.

? They are adding radar, though: https://electrek.co/2022/12/06/tesla-radar-car-next-month-se...
