It's not my opinion. Every leader in autonomous driving says that a camera only approach can do self-driving but CANNOT do self-driving safe enough to remove the driver from the car. So if you want self-driving with driver supervision, camera only is fine. But if you want a driverless robotaxi, then you need radar and lidar in addition to the cameras.
It has nothing to do with more complexity making it safer. Complexity does not inherently make a system safer. Adding redundancy in case the cameras fail, that adds safety. If your car only has cameras, then it is totally dependent on that one sensor working perfectly and never making a mistake. If that one sensor has a problem, which will inevitably happen at some point, the car could fail which reduces safety. If you only have cameras, what will you do if the camera vision makes a mistake? Or if a camera gets dirty? Or of the camera gets obstructed?Adding radar and lidar in addition to cameras means that your autonomous car can function properly even when the cameras fail. So, it should be common sense that you need another sensor to help out in case the cameras have a problem.
And no, you don't want unnecessary complexity so you will avoid adding too many sensor or sensors that will be suboptimal. But you still need redundancy. You still need a combination of cameras and some radar and some lidar, placed optimally, if you want to be able to remove the driver from your autonomous car.
