Tesla Autopilot drove into Wile E. Coyote-style fake road wall in the middle of the road in a camera versus lidar test.

    The problem is that at scale you can’t have every car on the road using lidar at the same time.

    They’ll mess with each other’s systems.

    Same with radar.

    So while this seems like a solved answer, it’s not necessarily as simple as it sounds

      This is objectively false. Early lidar systems did have crosstalk interference and mitigations have been designed and working for years.

      It’s like saying you can’t have WiFi cause if all your neighbors do it won’t work. As these systems hit the real world mitigations get designed to handle these types of issues.

        The mitigations work in small numbers, none of them seem like they would work in large amounts of traffic

      Again, also not true. Lidar and Radar systems use a special spread spectrum frequency modulation and they do not interfere with each other.

      I’m not sure that’s true. Has anyone punished a study on this? Lidar has far less “on” time than one would think.

      IMO what is required is stereoscopic image capture and processing - This allows instant distance measurement to every pixel of the image
