Tesla is a great at many things but managing customer/media expectations isn't among them. I'm sure Elon has the data and will tweet why vision is better, he may even back it up with really good data, but it's reactionary media management rather than preventative. How hard would it have been to write a press release explaining why they are removing radar, what it means to safety, and how it impacts the future of self-driving?

Tesla doesn't have a PR department. It was dissolved last year. https://techcrunch.com/2020/10/15/teslas-decision-to-scrap-its-pr-department-could-create-a-pr-nightmare/ https://techcrunch.com/2020/10/15/teslas-decision-to-scrap-i...

They are in a pickle due to the chip shortage. There are no good technical reasons for removing the radar sensors. What would they say?

  Nonsense. They have been talking about removing radar for a while, that was always part of the plan.

    There is a difference between not relying on radar and having it there to provide redundancy and removing the thing altogether and presenting a single point of failure that can cost someone their life. MobilEye for example can run on vision and radar independently and they have been for a while. The reason they don't remove one or the other sensors is to provide redundancy. When your tech can kill people, it's a good idea to provide redundancy.

      The redundancy is not free. The false positives cause the car to potentially react in the wrong way and that can also kill people. Tradeoffs have to be made in the real world. Why don't we force ever car to have radar, sonar, cameras, lidar and so on. Who cares what the cost is? If we can save a single life we should equip all 10 million cars that are sold every year with all of these things. This is not how safety works, if with vision they can hit the targets they are trying to achieve and radar causes issues, then removing it is a option. Radar also uses energy and is extra weight you have to transport and its extra cost. This is specially true that because of all their investment into vision their new pure vision solution is better then the old vision+radar solution.

        The phantom braking is not a radar issue, it's an issue with the vision system. That's why removing radar is such a monumentally stupid idea because Tesla's vision system has proven itself to be a pile of burning dog poop. If their vision system was actually good/safe and was truly unneeded then they'd have a stronger case for removing radar (but not a watertight case, because redundancy). As it is, their vision system sucks.

> Elon has the data and will tweet why vision is better, he may even back it up with really good data I doubt Elon has any sort of data. This is a way to maintain Tesla’s brand image during the radar chip shortage, and continue selling cars. Hell, even Tesla says vision-based proximity might not be fully functional for some time for new Tesla’s. Clear evidence that this is rushed and not ready.
