  • Not to downplay this situation because it is a bad situation regardless but looking at the multiple articles that they have released on this and the lack of video that they have provided regarding it, without seeing the video it's hard to say who's at fault here. Well aside from the driver who hit and ran obviously.

    It sounds like both vehicles had a green light at the intersection and I expect the second lane wouldn't have been able to see the pedestrian that was crossing in the first Lane to begin with. The article States the vehicle when it saw the pedestrian "braked aggressively" in order to try to not hit the person. I don't think that this is as simple as a oh there was a person waiting at the crosswalk so it shouldn't have gone, a lot of these intersections also have pedestrian lights on both sides of the crosswalk. Every article is blaming the autonomous vehicle, but I really don't think an actual driver would have done things differently given what has been released. In fact they might have actually made things worse by immediately driving off the person's leg/ankle instead of waiting for the lift.

    I'll be interested to see footage when it's released cuz I'm curious this was an actual mistake on the autonomous vehicles part or if this was a it did what it could not actually being able to be avoided

  • I think most computer vision cameras are fairly low resolution, so I'm not expecting the hit-and-run vehicle will be identified.

    • I'm under the impression they rely on lidar or radar even more than video/vision. I'm talking out of my ass though, I don't actually know

      • You're correct, Cruise is using LIDAR and RADAR systems. I used to work on Google's Waymo project, and Cruise is using almost identical tech in their SDCs (so much so that I believe there was actually a lawsuit about this), so I can speak to this a little bit.

        These cars use LIDAR, RADAR, microphones, cameras, and a few other sensors to get an accurate readout of their surroundings. The LIDAR is used mostly to determine the shape of things around it (and thus determine the type of object it is), and the RADAR is used to calculate the trajectories of those objects.

        The cameras aren't used for measuring 3D space (which is what Tesla is doing, and is a major part of the reason that Tesla's Autopilot is so laughably terrible in the SDC industry), but mostly for identifying traffic lights and street signs. Detection of pedestrians and other vehicles is done mainly by the LIDAR/RADAR systems, and these cars can still identify and avoid pedestrians and other obstacles with these even in the event that all of the cameras have failed.

        That said, the resolution of the cameras is still very decent. At the time I was at Waymo, the cameras were broadcasting to us in a crisp 1080 resolution (though I believe they recorded locally at 4k), even with the IR night-mode enabled. So to @swope's comment, the other car's plates were almost definitely captured.
