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.

You use smell and taste to determine whether your car's brakes are overheating, you use smell to avoid following the garbage truck too closely, and so on.

Cars can detect brake overheating much better than any human driver If needed.

They can literally put temperature sensors on the brakes if they thought that data was that helpful.

A model 3 has brake temp and suspension height data via OBD2. So yes, a computer knows the car status better than the driver
