One of the cool thing about the Waymo Driver is that it can be configured to work with different degrees of quality depending on the sensors available. In a low risk environment (e.g. closed to humans) like operating forklifts in an autonomous warehouse, it would work fine with just cameras. Waymo hasn't been very boastful to date, but some of the capabilities are hinted at in this interview: https://www.youtube.com/watch?v=d6RndtrwJKE
