It has been a problem, but it is definitely not an intrinsic defect of camera based solutions. The stopped truck example has been examined in depth with rooted Tesla's. The Tesla actually detects the truck, but fails to fully recognize the scenario and attempts to drive under it! See also, greentheonly's work on Twitter on researching this. Ignoring some stopped objects is only a temporary limitation.

I said it was a systematic defect camera based systems share, not that it was intrinsic to camera based systems. Camera based systems have much less information about object positioning than LIDAR based systems. They filter out non-moving objects because the vision processing algorithms are not sophisticated enough to distinguish between the background and obstacles. If they stopped for stationary objects in the road, they’d routinely stop because they mistook the background for a stationary object. That may or may not be a temporary limitation. It depends on whether vision processing becomes reliable enough where you can almost always distinguish an object in the road from an object in the background.

  > I said it was a systematic defect camera based systems share, not that it was intrinsic to camera based systems. And I'm saying that even that is incorrect. Here is a Tesla failing to stop: https://twitter.com/greentheonly/status/1134987596508143617 https://twitter.com/greentheonly/status/1134987596508143617 - The driver clearly noted that aiming for a less clear spot (dangling wires) triggered a stop. Here is another example, in which greentheonly has used root to overlay what the car sees: https://twitter.com/greentheonly/status/1135011184439169024 https://twitter.com/greentheonly/status/1135011184439169024 - It sees the truck but is treating some of the space under it as drivable space.
