This comes up basically everytime the Tesla Autopilot is discussed on HN since they rely mostly on cameras, except that they also have a front radar. In the end, we want self-driving cars to be better than human drivers, so they should also handle situations that humans are struggling with and additionally have some redundancy. Some things which are difficult to do for CV, detecting things in the dark for example, are trivial for Lidar. Radar on the other hand can provide accurate measurements for distance and speed of other vehicles, also independent of lighting conditions.
