Lidar is critical for any autonomous vehicle. It turns out a very accurate 3D point cloud of the environment is very useful for self driving. Crazy, I know.
Useful but not at all required. Camera + radar is sufficient for driving, and camera+ USS is fine for parking.
Radar is just cheaper than the number of cameras and compute, it's also not really a strict requirement.
Look at how the current cars fuck up, it's mostly navigation, context understanding, and tight manoeuvres. Lidar gives you very little in these areas
