    Full self driving itself isn’t a lie, just Tesla’s full self driving with only cameras and a ridiculous time scale is a lie.

    With lidar, full self driving will probably be usable in the next 10ish years, for at least most simple driving tasks. But every single Tesla only uses regular cameras, and that’s probably never gonna happen. Cameras are just not good enough. Elmo says things like “humans only use vision to drive, so cars can too”, but he’s not taking into account how bad cameras are compared to our eyes. The best cameras in the world don’t even come close to our eyes’ dynamic range, and Tesla is using cheap consumer cameras. Not to mention how quickly our eyes focus compared to consumer cameras (which is why Tesla cameras use a super narrow aperture, so they don’t really need to focus, at the expense of losing a lot of depth information and adding a lot of noise in low-light).

    Our eyes are also powered by our brains, another thing Elmo tends to forget. We can adapt to situations we’ve never been trained on, and we can make incredibly accurate predictions in near real time. Computers will eventually get there, but they’re not there yet, hence why Teslas have a tendency to drive full speed into obstacles they’ve never seen before (like an overturned truck).

    Computers need mountains more information than we do to make even close to the predictions that we can, and that’s just not something a Tesla with a few cameras can do.

      Awesome in-depth, thanks!

      And yeah, like I said, everything he says is a lie, even in and around SpaceX, which too is a shit show beyond first glance.

      This Fu ker should be in jail for life. No capital punishment, let him just slowly fade away, forgotten, in a cell
