This is a very interesting article and video interview with the CEO of Quanergy, Dr. Louay Eldada who believes automated vehicles will require video, radar and lidar operating at different wavelengths to provide a complete picture of the environment with redundancy.
Dr. Eldada believes that the automation process itself will be a continuum, the length of which will be driven by the cost curve for the technology. The greater the demand for the sensors the lower the costs of manufacturing for greater quantities which will stimulate more demand and so on.
