      The fusing step is very straightforward and pretty much how I imagined it would be done. This is new? Also I still don’t get how Tesla can take the stance that cameras only is the way to go... I really thought redundancy was a no brainer here...https://twitter.com/math_rachel/status/1204100054681870336 …

      Jason Antic added,

      Cameras 
Pros: affordable, well researched, have rich semantic info
Cons:
affected by weather/light, distort physical distances

      “Lidar is really a shortcut," added Tesla AI guru Andrej Karpathy. "It sidesteps the fundamental problems of visual recognition that is necessary for autonomy. It gives a false sense of progress, and is ultimately a crutch." https://arstechnica.com/cars/2019/08/elon-musk-says-driverless-cars-dont-need-lidar-experts-arent-so-sure/?amp=1 …

      ^^ this just seems like a really strange position. Why not both...? There are some things cameras simply can’t do!

      "(Lidar) sidesteps the fundamental problems of visual recognition that is necessary for autonomy." It's hard to imagine how a cameras + extra nonhuman senses (lidar or anything else) wouldn't be better than cameras alone. Bad optics if they say 'cheaper and good enough' I guess.

      That’s exactly what I think it is- spin on a decision that really revolves around trying to make this economically viable. That’s a laudable goal too but it isn’t going to be as well received.

          Especially considering adversarial examples in the wild, purely relying on lidar or cameras IS a death sentence to someone. Just a matter of time until catastrophic failure The “cons” of discrepancies between them are more ways for synergy & identifying uncertainty

          The most charitable way I could restate Tesla's argument: spending 100% of research on cameras will yield faster progress than splitting their resources between different inputs, but I'd still bet the real reason is cost in the final product they hope to sell.
