A combination of cameras, lidar, ridar, ultrasonic fused together have a strong sense of perception since they fill in each other's gaps. (short, long, different spectrums of electro-magnetic spectrum / sound).

The good news is they're all commodity hardware prices now.

Tesla removing radar and parking ultrasonic sensors was a self own. Computer vision inference is pretty bad when all the camera sees is a while wall when backing up.

Fog - Radar will perceive the car. Multi car crash, long range radar picks it up.

Bright glare from sun, lidar picks it up. Lidar misses something, camera picks it up.

Waymo has the correct approach on perception. Jam with sensor so they have superhuman vision of environment around.
