From an engineering perspective I would ask:
Can your sensor package understand the environment to the required (low) failure rate?
Radar/Lidar/Ultrasonic is going to give you information that your camera systems will not give you.
It does not matter if the delta of information is little. If this little is required because you can't obtain it otherwise, you still need it.
If you just rely on the fleet, you rely on the things you have seen.
What about the objects that you have not yet seen?
