The stuff that scares you may be the beginings of the technology thats actually needed to get to full L5. We just don’t know yet so anyone that is certain on the internet I would be skeptical of. The bet Elon is making is on pure vision which is a much different approach than Waymo and Cruise are taking.

It might be. But I find it difficult to believe that having fewer sensors makes things easier. I also just don't think the Tesla cameras have enough angular resolution to perform a lot of scenarios safely, like detecting a much faster vehicle in a short merge. (Note Tesla relies upon the front-facing radars quite a bit, too, so it's not really pure vision).

  Elon said they’re not going to need the radars going forward. I guess that makes sense if vision gets good enough but they’re going to run into issues like you said if camera placements and poor visibility. They should have stuck cameras facing the left/right from the furthest corners of the car so it can see around corners without inching into the street. But who knows, it seems like they’ve made good progress as is so well see. I don’t understand the people that think they’re never going to upgrade the camera suite though, cybertruck and the semi already have a new camera layout.

    > I don’t understand the people that think they’re never going to upgrade the camera suite though Well, they've committed an awful lot to current FSD customers that I think will be difficult to deliver upon with the current camera suite. I think LIDAR is a huge advantage. There's the direct benefit: you really know exactly where things are. But secondarily, you have ground truth near-perfect range data to use in training your vision system.

  The next beta is not going to use radar. Fewer sensors is much better for Tesla since they need aerodynamics and less power consumption for more vehicle range. Remember they are making a fully integrated product from the start, not bolt-on technology. We don’t yet know the limits of the pure vision approach. Elon is very confident in it and I want to see where it goes. Your comments about resolution may or may not matter.

I'll believe it when I see it, no matter what recent statements have been. > Fewer sensors is much better for Tesla since they need aerodynamics and less power consumption for more vehicle range. Automotive radars use like 10W. The least your car is using while driving is like 5000W. This may not be the best place to save power-- getting heat pumps on more vehicles and better ones than the present one would make a far bigger difference. > Your comments about resolution may or may not matter. If you can't see a car that will hit you when you commit to merging on a short merge, it is a slight problem.
