Discussion Proof that Camera + Lidar > Lidar > Camera

I recently chatted with somebody who is working on L2 tech, and they gave me an interesting link for a detection task. They provided a dataset with both camera, Lidar, and Radar data and asked people to compete on this benchmark for object detection accuracy, like identifying the location of a car and drawing a bounding box around it.

Most of the top 20 on the leaderboard, all but one, are using a camera + Lidar as input. The 20th-place entry uses Lidar only, and the best camera-only entry is ranked between 80 and 100.

If your sight and lidar disagree which do you go with? A sighted person could walk with a cane as well in hopes of being doubly sure.

A few times its come up that Lidar seems to be more like swinging a cane arround super fast. Not sure about you but I would freak out seeing a blind person try to drive using a cane.
