Unless I have missed something they are getting the cars over several years. A modified car (presumably during the manufacturing process), over several years, is very much reasonable. Radar and camera is part of the production of the modified car, LiDAR and compute system snaps into modified body. Waymo keeps control on their most important hardware. Seems very doable over several years.
