When I drive a Tesla Model Y under Self-Driving mode at night inside YellowStone NP, there is another car on the opposite side with a high beam turned on, and just near that car there is a bison on the road, the Self-Driving computer fails to detect the bison in the beginning, and too late to do emergency break, the car hit the bison after passing that car. The bison died but driver is safe, the front right head light part and right repeater camera was missing. It's very hard to see the bison in the dark when the other car turns on the high beam, for both humans and cameras, the self-driving without radar or LiDAR is not able to detect the obstacle at the blind spot. I want to report this accident as a reference, the car's self-driving software helped me avoid serious injury. The Tesla FSD(Full Self-Driving or Autopilot) is great but I still hope there's more sensor such as radar or LIDAR can be added to the car for better night vision self-driving. The car deemed a total loss and there is a video from the front dash cam record how this accident happen.
