LIDAR doesn’t stop them bumping into anything. LIDAR is a sensor, it doesn’t recognise anything or make decisions about steering, acceleration, or braking.

  You need more than the sensor, obviously. The point is that you don't need any AI to make a system this way that is substantially safer than a system based only on camera feeds and AI.

    Do you think Waymo using LIDAR means that Waymo aren’t using AI? Waymo are using AI.
    • amelius 11mo ago
      That's not what I'm saying at all. Waymo uses LIDAR to ensure safety. They use AI for most of the rest.

In this scenario, Waymo’s AI is executing thousands of steps in a row. The fact that it uses LIDAR for sensing doesn’t change that. It’s still AI driving you around no matter what its eyes are made of. Waymo is a counterexample to the point you were making and their use of LIDAR doesn’t change that.

          No because safety is guaranteed by the LIDAR and navigation is done by GPS+classical algorithms. Mistakes made by the AI can be overcome by those two non-AI approaches + reiterating the AI-based steps.

            LIDAR cannot possibly guarantee safety. It is a sensor.
            • amelius 11mo ago
              That's like saying an algorithm cannot guarantee safety because it is not an actuator.
              • JimDabell 11mo ago
                An algorithm controls the actuator. The sensor does not control the algorithms or the actuators.

                  Look, it is a hell of a lot safer to use an input that does not hallucinate objects than an input that does.
